Drusilla

Drusilla is one of three suspicious female monks encountered by the Avatar in the era of Serpent's Fang (the other two being Solaria and Rieya). She can be found in offering 'helpful' advice to the Avatar outside Issik's Maze.

Description
She did arrive with her sisters some time prior to the Avatar. While they did keep away from the fortress itself, their presence and hostility to Ophidian culture did agitate the garrison. However, a treaty was made, in that they would keep out any unwanted elements trying to enter the vicinity of the fortress, and in turn they could stay. The uneasy peace held for the time being.

Drusilla was very annoyed when the Avatar appeared, having become bored from waiting and did not like any jokes about her age. During conversation Drusilla called the Avatar a pawn of prophecy, making it clear that she thought little of the Ophidians, instead following a Guide, but was unwilling to go into detail. She tried to dissuade the Avatar from entering the maze, but nonetheless gave three hints about it: that one can reset the maze by killing oneself in the corner fires, that sometimes certain rooms have to be traversed twice and that mastering a level would open it up permanently.

After the Avatar managed to gain the Silver Seed, Drusilla and her sisters appeared to stop them. Thanks to Solaria's babbling, it was revealed they were actually working for the Guardian, and have been sent by him to prevent the Avatar from restoring the Tree of Balance. Drusilla, along with her sisters, was killed by the Avatar and party when they attempted to stop this restoration.
