Why this is hell, nor am I out of it.
Think’st thou that I who saw the face of God,
And tasted the eternal joys of Heaven,
Am not tormented with ten thousand hells,
In being depriv’d of everlasting bliss?
—Mephistopheles, Doctor Faustus

Estillor is an ex-Noblian demon. He didn't mean to be, honest. It just sort of happened.
