On her person, you find she's fairly well equipped, with a potion of heroism, 2 scrolls of magic missile, 2 scrolls of magic weapon, studded leather, +1 heavy crossbow with 20 bolts, a masterwork falchion, a cloak of resistance +1, and a gilt wooden funerary mask (worth 25 gp). Her belt pouch has 23 gp in it.
When you rouse and question her later, she tells you that she's a never of the cult of the forgotten Pharoah, and they have a camp on an island on the river. They seek the mask that Tabat wears and they also want to search the library for clues to the resting place of the Hakotep. She doesn't know much else about their plans.
If you go there, you're earned that there will be six cultists (less her), a sorcerer who leads them, and a hieracosphinx.
