Stardock

Stardock was an asteroid in the Tears of Selûne. It was connected to Undermountain through a portal known as the Rift.

Geography
The asteroid was hollowed out by a series of tunnels and chambers. The largest of the caverns was the asteroid's namesake: an enormous dock wide enough to moor a large spelljammer vessel.

History
In the distant past, the cave system of Stardock had been the lair of an unknown species of dragon. Sometime before the 11 century DR, Stardock was an outpost of the illithids from Glyth, dug by umber hulk slaves. The outpost was used occasionally by the mind flayers for the following 200 years.

Sometime in the mid-14 century DR, the Twisted Rune discovered the existence of the outpost and used a wish spell to create the Rift. Led by Priamon Rakesk and the alhoon Ralayan, the Rune raided and conquered the outpost. They subsequently used it as a base for magical research, kidnapping Halaster Blackcloak and imprisoning him there in order to discover secrets that might grant the Rune an advantage in their struggle against the Red Wizards of Thay.
