Ruled by Isis hundreds of thousands years ago, it was passed first to Demeter and then to her daughter Persephone.
When Persephone left the Olympian Galaxy, the planet was briefly under the Hermes sector until the Talos Collective destroyed its civilization.
The planet was later destroyed by Isis when she teleported her own planet in the same solar system.
The solar system was later assigned to Hebe. It's unknown if there are other inhabited planets in the same system.
