Humans have been visiting the Dorgeshuun mines for some time now, but no Dorgeshuun has visited the surface since the signing of the Lumbridge-Dorgeshuun treaty. The Dorgeshuun Council fears that the H.A.M group may be planning another attack, and want to send an agent to the surface to investigate. But they do not want to send someone to the surface without a guide...
Wander around the south of the stage, Zanik will spot a trapdoor.
Pick the trapdoor and go down. You'll need Zanik to kill the guards in this room to continue:
Walk west past the first guard and talk to him, then Zanik will shoot him.
Squeeze through the crack in the wall. Wait for the guard in the central corridor to walk by, then squeeze through the next crack in the wall. Run west behind the guard by the door and talk to him. then Zanik will shoot him.
When the guard in the corridor starts walking east, say, “Now!” and Zanik will snipe him.
Move to the eastern end of the central corridor, and talk to Zanik again. Tell her to wait. Then, run south to make the north-east guard follow you. Zanik will shoot him as he passes the central corridor.
For the final guard, go to the end of either of the passages, and talk to Zanik again. Tell her to wait, then go to the other passage, and distract the guard. Zanik will shoot him.
Listen at the door. A senior guard will appear and arrest you.
Pick the lock to escape the cell, then leave the hideout to find Zanik, dead. Take her body.
