Pathfinder (Wrath of the Righteous)
Worshiper of Demons. deceased
We killed her when we annihilated the shard of the warding stone.
Her name was mentioned in some of the letters that you have found. In the first letter it is said that she was supposed to find a sword for Stantoun Vhane. In the second letter, it is said she brought the sword to Aigon Topaz who then took it to Nyserian Manor.
According to the prisoner you picked up at the Tower of Estrod, she is into undead business, and she wears an armor made up of bones of those she killed. You encountered Jeslyn (and many other big bad creatures) in the big cave to which you teleported from the Gray Garrison, and it seems the rumors are true.
