Ducha was a title of nobility in the Hapes Star Cluster.
The Ducha AlGray controlled the Relephon Moons, while the Ducha Galney ruled on the world of Terephon. It is not known what sort of powerbase Ducha Requud had, but like the other two Duchas, she commanded her own combat fleet, consisting of Battle Dragons and other warships.
Reflecting the matriarchal nature of Hapan society, all three known Duchas were female. The title of Duch'da may have denoted a Ducha's heir.
