I like him.
First of all... You could. But you have to be aware of one, You don't know how. Two, alone you aren't as strong as when other Harbingers are near. So you wouldn't have that kind of strength by yourself. Three, you won';t have the knowledge on how to do it. Your powers will grow as time goes on, so by the end, it might be possible, but not anywhere else. And four, the resulting backlash would destroy you. All powers have a toll, like mine snaps me into different times, or makes me a different time. Yours could involve things altering about you, like say... You grow or shrink, or you turn colors... Or even, if it's really bad, randomly teleport to a pocket realm or something. You power is left to your imagination, but there is always an equal or greater cost to everything you do. I'll leave it at that for now.
