Mourning's Ends Part II (The Temple of Light), often abbreviated as MEP2, is the seventh quest in the Elf quest series. This quest is often described as challenging by players who have completed it due to it having, arguably, the most difficult quest puzzle in the game.

Description This chapter of the quest takes our hero deep under the mountains of Arandar to put a stop to the evil plans of the mourners.

If our hero is to succeed, they must solve one of the most complicated puzzles in all of Gielinor.

Length Very Long
Requirements

Recommended:

  • 60+ Agility icon Agility for lesser chances of failing obstacles (91 to never fail [1])
Items required

Recommended:

Enemies to defeat None (but powerful level 73 Shadows are aggressive to players inside the temple)

Walkthrough[]

Entering the temple[]

Items required: Full mourner gear, chisel
Recommended: Elf teleport crystal, teleport to Ardougne, food/prayer potions to run past high level monsters

Begin by speaking to Arianwyn in Lletya. He will tell you to go and stop the mourners from excavating under West Ardougne, and that you need a key from the head mourner to enter the excavation site.

Note: You will not start the quest until you get the new key from the head mourner.

Next, put on your full mourner gear and remove all of your other worn items (rings and ammunition/blessings are allowed). Bring a teleport crystal, and some food if you have low Defence or do not have 43 Prayer for Protect from Melee. Also, bring along a chisel. Go to the basement of the Mourner HQ in Ardougne, and talk to the head mourner.

He will give you a new key to the nearby tunnels that they dug to the Temple of Light. He will ask you to find the digging team, a group of slaves and mourners that have high enough Slayer skills to defeat the beasts in the area. Leave the head mourner's room and open the door on the west wall. Go into the tunnel. You will see level 182 Dark beasts. The beasts require a Slayer level of 90 in order to be harmed, and use both melee and magic - however, they only use melee unless you cannot reach them or attack them first.

Note: For ironmen with 90 Slayer, they can kill the dark beasts for the death talisman, which will save a lot of time further on in the quest.

Run past them (to the west, then take the southwestern turn) to reach the temple entrance. They hit hard; it would be a good idea to use Protect from Melee whilst running past. You'll see a cutscene; shortly thereafter, you may be attacked by level 73 Shadows. Search the corpses of the digging team to get Edern's Journal and a colour wheel. The wheel is unnecessary for the quest and can be dropped.

Read the journal, from there, go west and climb up the stairs. Go south, then climb up the ladder on the southern wall. Go north then take the stairs to your northwest down, then back up. Run as much east as is possible, then south to the crystal. Use a chisel on it to break off a piece. Teleport to Lletya, and go back to Arianwyn.

Black Crystal

The broken, blackened crystals.

He will summon Eluned, who will enchant the black crystal in your inventory into a newly made crystal (note: use the blackened crystal on Eluned). It will be used at the end of the quest. Talk to Arianwyn again; then, you will need to prepare for a long and potentially frustrating puzzle.

The light puzzles[]

Items required: Full mourner gear, the new key, rope. If you're planning to complete the puzzles in a single trip, bring a death talisman/death tiara and the newly made crystal too.
Recommended equipment: Weight-reducing clothing, high Prayer bonus gear
Recommended items: Prayer potions, stamina potions, food, summer pies/agility potions

If you want to attempt the puzzle in one trip, bring the mourner clothing, the new key, the crystal, and a death talisman. As you progress through the puzzle you will need an increasing number of inventory spaces free in order to hold the mirrors and crystals, which you will have naturally as you consume prayer potions and food. You will need 4 inventory spaces for the first steps of the puzzle, increasing to 13 inventory spaces open for the last step of the puzzle. Feel free to bank between every major section in the puzzle as the mirrors and crystals will be in the same positions you've left them if you decide to teleport out. However, you cannot bank the mirrors and crystals received in the temple, so prepare to complete each section from the beginning to the end before doing anything else.

It is highly recommended to bring some of the following: Prayer-boosting equipment, super energy potions, weight-reducing gear, prayer potions, Agility boosts, and food. If you find that prayer potions are too expensive, bring good armour and defence potions instead. It is much, much more convenient to buy a death talisman/tiara from the Grand Exchange, and to bring it if you have one. Otherwise, you will have to give an NPC a long list of items (see below) to get a death talisman. The death talisman is not consumed during the quest, and players can decide what to do with it after its role is finished.

Blue door[]

Crystal collector

The crystal collector is just east up the main stairs on the wall.

Go back to the Temple of Light. Go up the stairs and then go east to the crystal collector. If there is a beam coming out of the Pillar of Light, search it and take the mirror, then pull the crystal collector and collect the items inside. You'll get a yellow crystal and three more mirrors. You need to unlock the blue door with a yellow beam of light. The pillar next to the crystal collector has a beam of light flowing through it.

  • Put a mirror in it and reflect the light north.
  • Walk north to the next pillar. Add a mirror and reflect the light west.
  • Go west, add a mirror, and reflect the light south.
  • Go south to the next pillar. Use your yellow crystal on it to dye the light yellow.
  • Go south and put a mirror in the pillar. Reflect the light east.
  • If you took Agility potions with you, it is highly recommended to drink them before attempting the next obstacle.
  • This part can be extremely frustrating. You must get through an agility obstacle consisting of 9 handholds. They have an extremely high failure rate for players of low and moderate Agility. The higher your Agility level is, the better your odds of successfully completing the obstacles; at 91 Agility, the success rate is 100% for all handholds[1]. This also means your weight is not relevant in attempting this obstacle. If you fail, you will fall to the level below and be attacked by several shadows. If you do fall, simply return to the beginning of the obstacle and keep trying until you succeed.
  • Pass through the blue door to the east and open the chest. You will get two more mirrors and a cyan crystal.

Pink door[]

Go back to the crystal collector, and pull the lever. Collect all of your items.

  • Go west and put a mirror in the pillar. Reflect the light north.
  • Walk north to the next pillar. Add a mirror and reflect the light west.
  • Go west to the next pillar and use the cyan crystal on it to dye the light cyan.
  • Go west to the next pillar. Add a mirror and reflect the light north.
  • Go north to the next pillar. Add a mirror and reflect the light east.
  • Go east to the next pillar and add the yellow crystal. This will dye the cyan light green.
  • Go east and pass through the pink door. Open the chest to get more mirrors.

Yellow and cyan doors[]

Items required: Rope

Go back to the crystal collector, and pull the lever. Collect all of the items.

  • Put a mirror in the pillar giving out light. Reflect the light north.
  • Walk north to the next pillar, and use a mirror to reflect the light down (the floor below). When you search the pillar and rotate the mirror, the widest side of the mirror should be on the bottom.
  • Go downstairs to the bottom floor. If you did the above step correctly, you should see a little beam of light coming into the pillar north of the stairs. Put a mirror in it, and reflect the light west.
  • Walk west to the next pillar and using a mirror, reflect the light north (through a hole in the wall, a cave and another hole in the wall).
  • Go around to the pillar north of the one you just put a mirror in. Use a mirror on it and reflect the light up (to the floor above). If done correctly, you should see a little beam of light flowing up.
  • Go back upstairs to the middle floor, go to the north side of the temple and find the pillar with a little beam of light flowing up. Put the yellow crystal in that pillar to dye the light yellow.
  • There is a ladder on the north wall right next to this pillar. Go up the ladder to the top floor. Put a mirror in the pillar and reflect the light west. It should pass through a pillar that has a magenta crystal in it. The yellow light beam should go through the magenta crystal, creating a red beam of light.
Pillar of Light (NW)

The pillar emitting a red beam is in the north-west corner.

  • Go back down the ladder and go south. Just before you reach the south wall, go up the stairs on the western wall. Then, go all the way to the north-west corner. Put a mirror in this pillar and reflect the light south.
  • Follow the beam to the south-west corner, and add a mirror. Reflect the light down to the floor below. The fat portion of the crystal should be on top during the rotation screen.
  • Return to the stairs that brought you to this floor (next to the handholds). Descend the stairs, and travel west around them to a circular, dead-end room which you may enter by climbing over a low wall. Climb over the low wall and enter the circular room, where you will see a large hole in the floor with a rock directly beside it. Use your rope on the rock, and climb down. Go south-west, passing through the door to where you may open the chest to get a blue crystal.

Don't reset the system! Otherwise, you will have to repeat the previous steps.

Pillar of Light (Cyan)

The pillar is at the north side on the middle floor by a ladder.

  • Go to the pillar where you put the yellow crystal in during the last step (north side of the middle floor). Remove the yellow crystal, and replace it with the blue crystal. You should now see a blue light going up. The mirror you placed above this pillar during the last step will reflect the light west, like before. However, this time, a blue light will be going west.
  • Start to run south. Before you reach the south wall, again go up the western stairs. Then, go as far north as you can, as far west as you can, and all the way to the north-west corner. Rotate the mirror in this pillar to reflect the light down (the bigger side of the mirror should point east).
  • Go to the bottom floor (use the southern stairs down, and then the stairs near the crystal collector, not the room with the rope). In the north-west corner, pass through the yellow door by rotating the mirror south. Go south then east, then go open the chest to get two more mirrors and the first fractured crystal.
  • Go back to and use the crystal collector.

Pink and yellow doors[]

Crystal collector

The first pillar with a mirror reflecting the light north.

At this point you should have (10 x mirrors, 1 Fractured crystal, yellow crystal, cyan crystal, and blue crystal)

  • The first thing you need to do is open the blue door again. Follow the above steps to open it. Once you get inside, use your blue crystal on the pillar, then exit. Collect all your mirrors and yellow crystal by walking around and getting them by hand. Do not use the crystal collector! All that should remain is the blue crystal at this point.
  • Go back to the first pillar with the light beam shining up and add a mirror. Reflect the light north.
  • Go north to the next pillar. Add a mirror and reflect the light west.
  • Go west to the next pillar, add a mirror, and reflect the light up.
Pillar of Light (near Black Crystal)

The pillar just north-west of the black crystal is the one.

  • Go south, climb up the western stairs, and go northeast. Make your way to the pillar that is northeast of the northern stairs/on the other side of the little room near the black crystal. Add a mirror and reflect the light south.
  • Make your way south to the next pillar. Add your fractured crystal to split the beam into three parts. You will use one of these to open the pink door and the other to open the yellow door.

Yellow door part 1[]

  • From the fractured crystal, follow the beam of light south. Add a mirror and reflect the light east.
  • Go east to the south-east corner. Add a mirror and reflect the light down - it should show the mirror's big side facing west (not south). Go back to the fractured crystal that split your beam into three parts.

Pink door[]

  • From the fractured crystal, go west to the next pillar. Add a mirror, and reflect the light down (not south). It should show the mirror's big side facing east.
  • Go down to the bottom floor, and find the pillar with a little beam of light coming out (head south, then west from the stairs). You will see that a green crystal has dyed the light green. Add a mirror and reflect the light south.
Pillar of Light (SE)

The end result of successfully directing the green and the blue beams.

  • Go south, add a mirror, and reflect the light east. This will unlock the pink door.

Yellow door part 2[]

  • Go to the south-east corner. Pass through the pink door; then, add a mirror to the pillar inside. Reflect the blue light north and pass through the door.
  • Open the chest to get more mirrors and another fractured crystal.

Cyan and black doors[]

You now need to open two doors: a new cyan door and a huge black door, using everything you have. Go back to the crystal collector, and pull the lever. Collect all of your items. You do not need the cyan crystal for the last puzzle. It's easier to destroy it for space and for less confusion.

  • Go west to the first pillar, and put a mirror in the pillar. Reflect the light north.
  • Go north to the next pillar, add a mirror, and reflect the light down (wider edge facing south).
  • Go to the bottom floor. Go north, and add a mirror to the pillar with light coming out. Reflect the light west.
  • Go west to the next pillar, and add the fractured crystal with the bright side on the left and the dark side on the right in order to split the beam.
  • Go south to the next pillar, and add the other fractured crystal to split the beam.
  • You now need to get a red beam, a blue beam, and a green beam of light pointed at the column in the final room. This will make a new clear beam that you can use to enter the black door.

Green beam[]

  • From the second fractured crystal, walk west, put a mirror, and reflect the light up. This will make it go through the green crystal.
  • Go to the top floor from the southern ladder on the middle floor. Go north and then west one pillar, add a mirror, and reflect it west.
  • The light will then reflect off of a mirror already in the final column and go down. It will now be in the final room pointed at the final pillar.

Blue beam[]

Pillar of Light (Fractured Crystals)

The first fractured crystal is on the ground floor north of the stairs, and the second is south of the stairs.

  • From the second fractured crystal, which is on the bottom floor south of the stairs, walk east. Add a mirror to this pillar and reflect the light up.
  • Go to the top floor. Find the pillar with a little beam of light coming up and add a mirror. It should be directly south of the black crystal. Reflect the light west.
  • Follow the beam of light to the next pillar. Add a mirror and reflect the light north.
  • Follow the beam of light to the next pillar and add a mirror. Reflect the light west.
  • Go west to the next pillar. Add the blue crystal to dye the beam blue.
  • The blue beam will then reflect down off of a mirror already in the next column. It will now be in the final room, pointed at the final pillar.

Red beam[]

  • From the first fractured crystal, which is on the bottom floor north of the stairs, walk north. Add a mirror, and reflect the light up.
  • Go to the middle floor, and find the pillar with the beam of light coming up. Add the yellow crystal to dye the light yellow.
  • Climb up the ladder (the one on the northern wall of where you put the yellow crystal, not the one to the south) to the top floor. Add a mirror to the pillar and reflect the light west. It will go through a purple crystal, where the blue and yellow will cancel each other out, leaving you with a red beam.
Temple of Light final pillar

The puzzle has been completed!

  • Go back to the middle floor. Go to the south end, climb up the stairs, and make your way to the north-west corner. Add a mirror and reflect the light south.
  • Go south to the next pillar. Add a mirror and reflect the light east. It will now be in the final room, pointed at the final pillar.
  • Go down the stairs in the middle of the top floor; then, go down the next set of stairs. Go through the cyan door. Turn the mirror towards the final pillar to merge it with the other two beams. It will be pointed at the black door. If you didn't bring a death talisman (or tiara) with you to finish the quest, then: When you're ready to leave, make sure to turn the light back towards the entrance door, otherwise to get back in here you will have to either do the whole thing again or go through the Underground Pass to get back.
  • Pass through the now white door.

The death altar[]

Items required: a death talisman/death tiara OR the 50 items below (suggested only for Ironmen due to the tediousness of this). If you bring the death talisman, take the newly made crystal too.

You can skip this whole section if you have already bought/received a death talisman or death tiara.
Temple of Light death altar

The death altar.

After you go through the final door, talk to the dwarf Thorgel. You will ask each other how you got to the altar, and he will reveal there is a passage from the Underground Pass created by him and his companions. You will ask if he knows Klank, after which he will realise you are the one who slew Iban. Because of this, he agrees to trade you a death talisman in return for some supplies.

He gives you an item list that tells you what you need to get him. By bringing Thorgel each of the fifty items on the list, you will be able to obtain a death talisman.

The needed ticket is chosen randomly.
The needed book is chosen randomly.
All of these books can be found in the bookcases in your house.
The needed key is chosen randomly.

You can give these items in more than one load. WARNING: If you teleport out, make sure you turn the mirror towards the cyan door first! Otherwise, you'll lock yourself out and you'll have to go through the Underground Pass and enter the tunnel inside the dwarf camp or redo the final puzzle. The entry at the dwarf camp is most easily reached from the Lletya village, which is fairly close to the elven land entrance to the Underground Pass. Doing the Underground Pass in reverse to get to the dwarf village is a lot easier. The tunnel is located directly south of the main building. It is not marked on the minimap, so it is rather difficult to see.

The power of death[]

Temple of Light repowered crystal

The temple's safeguard is now restored.

Use your death talisman on the death altar or wear your death tiara, then use the newly made crystal that Eluned repaired for you on it to charge it. Exit the death altar, and then exit the final chamber and make your way to the black crystal that you observed at the beginning of the quest. Use this charged crystal on the black crystal. This will stop people from entering the temple for another thousand years! Go back to Lletya, and talk to Arianwyn for your reward.

Congratulations! Quest Complete!
