#Find the book that Dirin Thilae references.
#*For good-aligned characters, a copy of the book is located in the South Qeynos mage tower (red teleporter), down the stairs, on the floor between Aristide Calais and Rune Shimmerstar.
#*For evil-aligned characters, a copy of the book is located in the Academy of Arcane Science in North Freeport, a small black book standing on edge on one of the tables on the first floor. The North Freeport book is leaning against two other stacks of books behind the sage..
#**You can pick up the book in your friendly city no matter which faction you are working with.
#Speak to Dirin Thilae again.
