I'm a Lot

A shaft of empowerment surrounds me.
Escape in an uptake to cloud
Could stave the devourment that found me
Innately.  Yes, I'm out of shroud.

Dense vapor above would be extension,
A haven, prosthetic success.
I'd shape an incredible invention,
A theropod jaw must impress.

Snap down from the sky a decimation!
My nimbus is nimble to kill
The bandits who brought their mastication
To crumble the building of will.
