Today's tables are ones I started a while back, and recently pulled out of d30 Development Limbo. They're based loosely on Appendix D from the DMG ("Random Generation of Creatures from the Lower Planes"). The funny thing is, just as I was getting close to finishing these up, Steve Marsh sent me his "Abomination Generator" pages from the Shattered Norns project I'm helping with. Abominations are MUCH different than fiends (demons/devils/daemons), and his tables produce some FREAKY-looking stuff.
But I digress.
These pages (please note there are 2 separate downloads for this) cover everything in the DMG Appendix D, and then some. I'm not saying they won't change or get updated at some point (which is the case for all the d30 charts I post here); e.g., I'm thinking about adding psionics in there somewhere. But these will get you well underway should your game for some lower planes creatures.
BTW, if you don't feel like rolling a d30 (not a situation I can imagine, I assure you), then check out the automated generator over at Land of Myriad.
