There is a new IWDEE quest available at Weasel Mods. Perhaps one of the biggest ones for that game. 

The War of Bloom and Rot is a quest mod that introduces a new quest of a significant size. Explore twenty new areas and face powerful enemies as you try to return from the underground system of caves. To leave, you may need to stop a war between the myconids and another, powerful entity--hungry and with a plan of eradication of everything and everyone on her way.

The quest begins after you find Krilag, kill him, and read a journal that he has. It shall reveal a new area, and your adventure should start there. The quest was created with experienced adventurers in mind - while it is possible to set off to the new area right after Krilag's death, it may be easier after leaving the Wyrm's Tooth area.
