ABERRATIONS
Bug people, things with too many mouths/eyes/tentacles, Eldritch Horrors, Cthulu-type creatures, and other things that should never have come into being.

CHAOS (Vanilla)
Anarchy!

DRAGONS
Along with the obvious, also includes weaker cousins. Treasure hoards, anyone?

DEMONS (Chaotic Evil)
Destroy everything good, cause pain and suffering! Take a soul, grow in power! Good thing mortals love bargaining with their souls.

Corrupt everything good, twist and trick mortals into their own undoing! Pain gives them strength. Contracts with them are common. They follow the rules, but usually that ends in their favor.

EVIL (Vanilla)
I'm just a powerful dude who wants to rule the world. Face my minions!

FEY
Mischievous normally, much more trouble when evil.

LAW (Vanilla)

OUTSIDERS
The planes of Earth, Air, Fire, Water, Heaven, Hell, Law Chaos, et cetera... everyone wants a piece of the Material Plane.

UNDEAD
From mindless Zombies and intelligent Vampires to Lich Wizards

UNDERDARK
Dangers lurk deep beneath the surface

WARS
Goblins VS Humans, Orcs VS Elves, Kingdom VS Kingdom, et cetera
