Here goes some that popped into my mind. Maybe one will ring well or they'll collectively give you inspiration or something.

I'll attempt to capture your description in a name by listing a few that I think bring to mind something powerful, but not necessarily evil.

Armok (props if you know where this is from)
Yaka
Marmaros
Harban
Dromar

My love for mythology lends me to suggest Tiw, or some derivation of that name (Tyr, Tiwaz, Tue) as well. He was one-handed the Germanic god of war and honor, and Tuesday is named after him.

I'm not sure what sort of theme that you were going for, but I thought of a few oriental-sounding names as well that might work.

Fu
Jin
Kai

A few others came to mind, but they might be too...fantastical? Grandiose?

Dal'Rend
Remonis
Yokuda


Any of those sound good?
