Interesting fantasy creatures?

Sooooo. *rubs hands together*

I am working on writing a fantasy story about two siblings who are tasked by the Maker (God, obviously) to keep the crazy world they live in under check. After all, with such huge beasts as dragons and sea monsters, you’d need to some extraordinary people to keep from these creatures from, um, destroying everything.

There is literally no limit to the kinds of creatures that I want to put in this book. Vampires. Mermaids. Vampire mermaids. Wyrms. Hobbits. Ghosts. Werewolves. Unicorns. Pretty much anything. I am combining traditional fantasy (dragons, etc.) with today’s fantasy (vampires and werewolves and all things odd), plus any other kind of fantasy there is.

So! If anyone would like to, you can suggest literally any kind of fantasy creature and I will more than likely include it in my book.

So far I’ve got:

– Minotaurs (and mermaid minotaurs)
– Werewolves (and weresharks, in the mermaid world)
– Vampires (and vampire mermaids)
– Fairies (and fairy mermaids)
– Dryads (and – okay you probably know that I have a mermaid version of this as well)
– Medusas (I don’t even need to say it)
– Dragons (Yep – they’re basically just huge hulking wingless sea monsters, though.)
– Wyverns
– Wyrms
– Drakes
– Amphitheres
– Lindwurms/Lindworms

Any assistance would be totally awesome!
