I nearly wrote this entire book. The adventure “Endless Night,” wherein you infiltrate a drow city disguised as drow, is mine. The article “Zirnakaynin,” detailing the largest city of Golarion’s drow, is mine. The mini morlock adventure “The Blood Below” is mine. I even wrote several of the Bestiary’s monsters, the omox, mothman, and deep crow. That last monster is worth special mention as it’s a creature the crew at Penny Arcade gave us permission to stat-up, an underground dwelling crow-dragon-abomination guaranteed to ruin deep-delving heroes. There was a point where I was intent on writing every page of this product, and while that didn’t shape up, I got pretty dang close!
