Pfff. There are many devils in Hell.
What you've got to watch out for is Urizen and Lucifer. I told Hades about keeping them locked below Tartarus but noooooo, he just had to let Lucy out to come to his bi-eonic and all Hell broke loose.
Now I'm stuck down here, below Urizen in the lowest levels of hell, while he's off destroying souls left and right, Lucifer's building her armies to conquer heaven and that moron Osiris is still stuck in the lobby trying to stop Cerberus barking.
I swear to God, if lust and carnality weren't a sin on Earth I don't know how I'd pass the time in Hell.
Fortunately we get broadband.
