It's really pretty all over the place, to be honest. Shi has control over smoke and illusions, Xulcuis has poision and illusions. It's mainly darker energies. Faulathi's depend more on physical energy. Lamirutu have different powers as well. For an example, Anya is kind of like a "water bender" type of thing. But she can't fight with her powers unless she has water near her, she can't just create it.
