According to Sagittarius Sisyphus's investigation, Catalania was once a thriving Roman city that was completely destroyed by the "gods of dream" associated to Hypnos (specifically, Dream Oneiros, as hinted in a drawing). A long time after the city's fall, Black Terror Felser released Phobetor from Athena's seal, and used the god's power in an attempt to revive Mine and make her dreams come true.
