Grave

Hmm. I'd be down with that. Just remember my suggestions are normally awful in hindsight. Not that I've ever looked back.

I like the name ^^ It gives a kind of electric feeling to the name

Not only that, but it also sounds a little like 'Tempest'

Ooh, good point. Tempest is a pretty awesome name in and of itself, very true... Well, I leave it to you to decide for yourself from here, I did my best! :D
