Hydran Kingdom (Space Trek)

The Hydran Kingdoms are the ruling body of the hydran species. A race of short, three legged, two mouthed, methane-breathing aliens with three tentacles for arms. The Hydrans live on the far side of the Klingon Empire from the Federation. Twice in their history have they been conquered by the Klingons and Lyrans, and twice did they draw their forces in the distanct Old Colonies to re-take their home worlds.
