Demon final boss: Jaxon

Demon final boss, ancient, overwhelming, and dark

Prompt: A deep, terrifying male demon-lord-final-boss voice, ancient evil at the height of its power. His cavernous register booms with world-ending menace and cosmic contempt, treating the heroes' final stand as a mildly interesting diversion, malice absolute and patience infinite. Overwhelming, magnificent, and utterly dark. The last boss, throne wreathed in shadow.

Script: So, you've reached my throne at last, little heroes. All that struggle, all those fallen friends, all to stand trembling before the one who was old when your gods were born. Do you feel it? The weight of the dark pressing on your chests? That is not fear.
