The Siren III was a heavily modified Aavman Extravagance Model 11-S Space Yacht owned by Leger DeMain. The ship had been modified to allow it to service as a theater. The bow had been rebuilt to act as a stage and many of the original cabins had been converted into dressing rooms and prop storage. The upper level served as living space for the performers. When landed a large section of the performance area of the ship could be separated from the rest of the ship and moved around to use as a stage. One of the ship's escape pods was actually a disguised mini-shuttle for Leger's private use.
