Bring the Lorgalis Manuscript to Gerrig Bonegrip in the Forlorn Cavern in Ironforge.
As you might know, I collect lore. Old lore. Powerful lore. Lore that opens doorways, and lore that can awaken Those Who Sleep.
There are rumors of an old piece of lore, the Lorgalis Manuscript, at the bottom of Blackfathom Deeps in Ashenvale. That place is the old dwelling of long-dead elves. Elves who held great knowledge before their city fell to ruin.
Search Blackfathom Deeps for the manuscript. Do this, and I will not forget it. Not even after ... the end days.
