It would be kinda cool if they had powers...
I'll just do powers for The Quartet, as I call them...
Scenario One: Element Control
Alek: Earth
Deryn: Air
Newkirk: Water
Lilit: Fire
*cough elemental rant*
Scenario Two:Fantasy MMPORPG
Alek: Knight (royalty)
Deryn: Mage (I would so welcome her as a fellow mage! she'd be a good one)
Newkirk: Knight (middie)
Lilit: Rouge (no explanation needed) (wait, is that how you spell it?)
Anyone got anything else?
