Pen, (without taking into consideration his evil nature, and just for the education of those in the forum) I believe there are a couple of things Kariska( I ) can shed some light on. Namely,
Shriekvra, being the Goddess of Evil, I doubt Pen would want much to do with her anyway.
The Adelfi Orko, which I am the only one currently who knows anything about them, not to sound snobbish, but I was the one who made them up after all.
Also, if I may help with the more evil of the magical/supernatural races, namely, necromancers, mages, werewolves, shades and warlocks.
Now, all the things above are strictly evil. If I may, I believe I have some valuable input concerning these particular areas, me being the Lord of Darkness after all.
