Princess Astrid is the daughter of King Vargas, the ruler of Miscellania. She lives with her father and her brother Prince Brand in the castle on the western side of their island. Male players must get her to agree to marry them during the Throne of Miscellania quest, although they don't get married immediately. She also features in the Royal Trouble quest. She is rather vain (a quality she shares with her brother) and loves flowers and archery.
She appears to be wearing an Armadyl pendant, a studded body of some sort and a pair of climbing boots.
If the player uses the Make-over Mage to change gender after getting engaged to Princess Astrid, she will say "Now please, find some way to turn back into a man..." if the player talks to her.
