In Forgotten Realms lore, what gods or deities make their home in one or more layers of the Nine Hells? (Asking for all editions of the D&D).

I get that each layer is ruled over by a "lord", which is a very powerful devil (like Mephistopheles for instance), but are there any gods that live in the Nine Hells? Surely there's a Lawful Evil deity that has a cottage in Avernus, along the shores of the River Styx?

PS - I'm aware that in 5e lore, Asmodeus is now a full-fledged god.
