"The Pit" in Sandpoint Hinterlands map or adventure?

[Guang]

Has "the pit" ever had a map, detailed description, or adventure done for it, official or otherwise? The one in which the Sandpoint devil lairs, with a ghoul temple, goblins, derro, gremlins, dark folk, and troglodytes?

*bump*

Also note the Pit hardly tops out at the level/challenge rating of the Sandpoint Devil:

Spoiler:

Kanker the ghoul alchemist is CR 12. The being known as Red Bishop is also involved, at CR 15. Finally, Uvaglor himself is CR 20.

Just saying this since I've seen the odd homebrew map of "the Pit" that in reality is just a low-level upper dungeon and not anything close to what makes the Pit special at all. (Nothing wrong with a romp down a hobgoblin-guarded dungeon; but it's hardly unique to the Pit...)
