DnD homebrewing and campaign designing
(ttrpg.network)
A place where Game Masters, Dungeon Masters, Storytellers, Narrators, Referees (and etc) can gather and ask questions. Uncertain of where to take the story? Want to spice up your big baddie? Encounters? That player? Ask away!
And if you have questions about becoming a Game Master you are most welcome with those as well!
Rules
I'd recommend checking out the AD&D 2E Planescape campaign setting specifically. It's basically THE "alignment matters" setting in D&D history, and just great fun in general imo.
