The Coalition's War
The seer of Monadhan.
Sarissa is a seer of great talent, but her oracle-like wisdom is limited only to the domain of Monadhan. She knows almost anything worth knowing in that place, but her powers are useless in any attempt she could conceive of to escape. Instead, she contents herself with extorting the people around her for cash and goods, and is easily the richest person in the shantytown of traitors.
