Publication history
Lords of Madness was written by Rich Baker, James Jacobs, and Steve Winter, and was published in May 2005.

This book is part of a series of books regarding specific monster types, which includes the Draconomicon and Libris Mortis.

Rich Baker explains how the book's designers chose the creatures with which they worked: "The best master aberrations we identified were the aboleths, beholders, and mind flayers. They're highly intelligent, they enslave other monsters, and they're particularly inimical to human life and society. Beyond those three major races, we found a couple of others that shared some similar characteristics but were not as iconic to the game -- the neogi and the grell. Finally, we created a new aberration just for this book, the tsochari. As the lead designer, I divvied up the book into assignments for Steve and James. Steve got mind flayers and neogi, James got beholders and aboleths. I took the grell and the new race, the tsochari. A fair amount of that decision-making was driven by the physics of carving up a book for three designers to work on, but I did decide to hog the new race for myself. I wanted to take a shot at 'em."
