A planetoid was located in the Cerberon system, orbiting the Cerberon singularity black hole. Yrica Quell, Caern Adan, and his unique IT-O crashed onto the planetoid after escaping the destruction of the Lodestar. The planetoid contained a Sith tower located on top of a mesa. The tower was laced with sophisticated biosensors that were designed to scan for a specific signature, perhaps biological or physiological, that also served as a locking mechanism for the structure. The tower was eventually opened by Yrica Quell, and she escaped the planetoid in an advanced starship with cloaking technology.
The planetoid first appeared in the 2020 novel Shadow Fall, the second volume of the Star Wars: Alphabet Squadron trilogy which was written by Alexander Freed.
