Description
The heroes who first imprisoned Greenscale defined their age. You have earned the favor of all of them save one. One who is lost to us through her noble acts.
The stormcaller Amunet constructed the prison of Greenscale using shadestone, the touch of which corrupted her remains. We need to separate the witch of ice and storm from the undead monster that wears her bones. Only Luminary Yentia in the Chancel of Labors possesses the means to save her, the Icewatch's most sacred book.
Upon completion
The Grimoire of Ice and Storm would indeed be able to separate out the stormcaller from the lich. But to do so you must take the book away from us.
To the Icewatch, this book is sacred. These are the rituals that protect us from the demons that haunt these mountains. Without them we leave ourselves open to corruption and death. We can only give it to one who we honor.
