I'd only made the Baator and Abyss symbols (copied really, from a Planescape poster I have from the setting boxed set) for my Spec the Damned to show in his character sheet (the original PBMB version of him), but I decided toe expand and make all of them just for fun. So here they are. If you wanna use any for anything go right ahead.
The Gray Waste:
Just to clarify, I don't claim ownership to the original symbols, that would be TSR. I just remade them in my MS paint program.
