It's called the Void Digger, and it's super sw33t, yo. Thing can accelerate to above 100mph after squeezing the gas, and it has a few built in technology junk. Squeezing the left handle blasts plasma rockets from between the two split parts you can see in the front, and the vehicle moves around by levitating, not using wheels...because it has none. It's materialized from a dark blue rune he keeps on the palm of his right glove. Squeeze yo' hand, form an orb of artificial blue flames, throw dat 'shizz on the ground, and bam, the Void Digger's right there, revving and ready to go.

That's the description, at least. Custom-built by Grave himself. He can build others. Thinkin' 'bout making an anonymous business for custom weapons and vehicles one day. Maybe. 

I'll edit that into his CS.
