Awful Shape, what art thou?

Awful Shape, what art thou? Speak!

DEMOGORGON
Eternity – demand no direr name.
Descend, and follow me down the abyss;
I am thy child, as thou wert Saturn’s child,
Mightier than thee; and we must dwell together
Hencefoth in darkness. –Lift thy lightnings not.
The tyranny of Heaven none may retain,
Or reassume, or hold succeeding thee...
Yet if thou wilt–as ’tis the destiny
Of trodden worms to writhe til they are dead–
Put forth thy might.

on Prometheus Unbound, Act III, Scene I
