Gnoll Outpost
I wanted to find a middle ground between a rough-hewn natural cavern and a fortified tunnel complex, because let's be honest - I've probably done enough kobolds.
Gnolls were a surprising and welcome possibility, as they're not typically civilized enough to go in for fine tunnel work; that said, as slavers, they're probably in a position to modify their environment to suit their whims. Well, THEY wouldn't, but it would happen.
Also, this was made with a mind for fans of a certain popular actual play series - if you need a base for some regular gnolls or vicious slavers, this will do just fine!
