Demons of Hell and the spirits they command

[nico.carlton]

How does this all happen? Do they command forces astrally? How does Hell look like? I like to imagine architecture from the High Elves of Lord of the Rings: Fellowship of the Ring.

Also, does Lord Lucifer and the Gods of Hell all live physically in the same "town"? Planet? Oh how I wish there was a biography of our father and the demons

All info appreciated
