Well, there were no orcs at the time, and fantasy doesn't make orcs out to be demons usually, so I couldn't predict that.

The orcs are on the Original Post, they're not demons but rather a vile race that worships the demons and often does their bidding which includes summoning new demons into the world.

The revenants have a consciousness of their own aimed toward violence, but are eclipsed by the host's echo early on in the life cycle.  The percentages lean in the revenant's favor as time passes.

So the older the revenant is the less it is consumed by the personality of its host? Though it is always driven to kill a person that somehow wronged its host (most likely leading to death), the longer it goes without doing this slowly drives it mad? Yeah I can work with that. Of course it'll be severely looked down on by other demons but that's always fun.

I plan to make another demon or two for each classification.  I would be excited to see others putting forth a few, though.

If anyone else is interested in adding to the Infernal Codex feel free to post ideas here and I'll take a look at them.
