Yes, it hosted the haunted leviathan patrol for season of the haunted. With the storyline being that Calus was trying to cease control of the Lunar Pyramid and nightmares on the moon. The season ended with us kinda drawing, Calus’ conciseness was able to synchronize with the black fleet but failed to retake the lunar pyramid and nightmares, leaving his ship the leviathan abandoned in lunar orbit where Eregore fungus continues to contort the ship. Since then the Leviathan has been largely left alone.
