Monster Madness

Since the creation of the Chaos Arcane Fulcrum I've been thinking, where could I go from here? The responses I have gotten from the Fulcrum seem to give me the idea of creating a Great Chaos Spawn/Giant Spined Chaos Beast or even a Jabberslythe. I do want to craft a Crystal Devourer, a magic eating beast from one of my own story lines. Hmm....what other things could I create?
