The Society of Brilliance are a sect of highly intelligent monsters based in the Underdark, who've made it their goal to try and solve the problems the Underdark faces. One such problem is a lack of information. Many visitors from the surface have been descending into the depths as of late, but don't seem to know much about the Underdark, and as such get themselves into quite a bit of danger. As the Society of Brilliance is too busy to spend their time tracking down all these adventurers to make sure they know enough to not get themselves into too much trouble, they have decided to release a series of guidebooks that teach about many different aspects of the Underdark, from species of monsters to the religion of the races.
In the Society's of Brilliance's Guide to the Underdark: The Umber Hulk, you can learn a bit more about the surprisingly intelligent insectoids, as to better your understanding of them.
This guidebook contains extra lore on the normal Umber Hulk, such as their creation, worship and mating ritual, as well as lore and statistics for three new species of Umber Hulk; the deadly Horrid Umber Hulk, the aquatic Vodyanoi, and the intelligent psions that are the Psi-Hulks.
