Twilight.
And to Hell with the Dawn/Dusk thing...if I choose Twilight, then I walk in the liminality betwixt light and dark. I'd use both powers for my OWN purposes, which can be judged good and/or evil depending on the person judging my actions. I would choose Twilight, but I'm not going to go into detail with Dawn or Dusk or whatever.
Or maybe I'd choose an entirely different path. ::Shrug.:: Why do the only roads have to be Light, Darkness, and Twilight? What about something like Ether/Aether/Nirvana/Divinity, something that is above implications of "sides"?
