Eth
The one and only moon that orbits Ellienias. It appears to be in a constant crescent shape with a star in the "hole" of it, but it doesn't have said hole. The star is said to be a portal to the Etherealm, but no one can really prove it. The portal only appears when you're within Ellienias's atmosphere. Any approach from the planet via shuttle or what not and the portal seems to dissipate once a breach of the atmosphere is made. This makes most people assume that it's just an myth of sorts.
Other than that, there was an incident in which the Gremkin Pirate Corps tried to inhabit it for resources and base operations and all that, but the Interplanetary Law Enforcement Agency located on Ellienias put a stop to that quick. So, it's not terribly remarkable outside of that.
