Chronicles of Khaldun: Crux of Eternity
Formed in the wreckage of a crashed alien airship, Skyfall is a small village of Purple Men in Carcosa. With the assistance of the Planar Trade Consortium, the Shields of the Sorrowfell, and the Mourners of Saerun Road, the Planar Trade Consortium hopes to expand Skyfall to encompass the entire upper level of the wrecked vessel, to be used as a base of operations for dungeon delves extending into Skyfall Delve, the ruins beneath Skyfall.
Interested parties are directed to the campaign, Old Country for No Men for further details.
(For those of you playing at home, Skyfall Delve is located in the mountains south of the Radioactive Desert and west of the Blighted Lands. It is likely somewhere in the vicinity of Hex 1804 of the official Carcosa map.)
