Halflings

While their home planet is not as advanced as other species, Halflings were privies into the space race visiting races who made strong friendships with the kind and fun loving Halfings. Most halflings find it difficult to find a home in a static location, opting instead to live inside huge vessels or smaller freighters converted to suit their needs as drifting farmers or handy workers.

Workers of the Cuth
A communist union of Halflings across the Galaxy that wished to have a voice among the Tiamat Empire. Being a race of adventurers and taskmasters they have a knack for filling needs and getting by in even the most dire situations. You'll never see a Halfling with a string of bad luck.

State Maxis
Those who remained in their home system of Maxis still used the technology offered by the Tiamat Empire to better strengthen their home from aggressors and from within with a better lifestyle. It's rare to see a member of State Maxis outside of Maxis, but on the off chance you see a fleet they'd be military personnel working under Tiamat.
