Confessor's Prayer Book

The Confessor's Prayer Book is provided as an objective for The Light's Mercy.

A character must have completed the achievement or  to be offered that quest.

The book is used on Slain Tualiq Villagers, which can be found all over Hrothgar's Landing. As the book has a ten-yard range it isn't necessary (most of the time) to even bother aggroing nearby kvaldir to free the spirits of the tuskarr.
