[@Rune_Alchemist] I'm pretty much down for all your suggestions. I've always thought Edolas was a boring Arc in Fairy Tail but for the sake of Eliza, I'm good to go  :) 

As for the vamps and werewolves... We could def make it that its some kind of Lost, Caster-type magic. I've seen it done before on a different site I use to RP on. Also I have an idea about magical beast created from the Source magic, I think it was called The One Magic (supposedly the manifested expression of love, aka the Essence of Magic itself). 

I haven't got a name for them but perhaps they could be named after the countries on Earthland or something ancient like that. 

Anyway these beast are essential for magic-use. One could govern holder-type magic, another caster, and the last Ancient or Lost Magic. This triumvirate of sorts are undetectable, hidden by magic beyond even Zeref. Created by [i]The Visitor[/i]... 

And that's all I got.
