Teaching new tricks to old gods

[Bohandas]

^That's a nice Lolth, you should write it up.

However this Lolth is no drow goddess and Gruumsh is already doing what you describe.
...
Anyway, I tried to get a Mystra up here but failed. She's far too tightly tied up in FR stuff of dubious quality, just like Cyric, and removing all that stuff just makes her boobed Boccob. Was a bummer.

Therefore, I decided to put my huge list here. Maybe it'll generate some recommendations and ideas. It's a list of bona fide DnD gods of variable fame that I'm trying to whip into a satisfactory cosmology( with commentary). Deities been mentioned until now are guaranteed to be in but even they're not set in stone. I also looked up the noobs of 4e, some of them do have potential.

Spoiler: huge
