Mobius System planets

Planet Wisp: Home to the Wisps, but there have been rumors of Wisp hybrids being made from other creatures who come there.

Eclipson (fan made planet): Home to the Black Arms race, which is ruled by Black Doom. It's an extremely harsh and hostile place, and it's rumored they may be allies to the Sith.

Green Gate: Home to Seedrians, like Cosmo, Green Gate was supposedly destroyed when it's seed was taken away. Somehow, this planet is back from the dead.

Enjoy your time here and watch your back in this system.
