Ur-Metheisn was a series of shipyards located above ch'Rihan and was noted as one of the largest orbital ship-servicing facilities in known space.

One of the loading bays was half a Stai wide and was one of twenty docking and loading facilities that were arranged around a vast spherical central core which was big enough to hold the largest vessels within the Grand Fleet. Neither the Klingon Empire nor the United Federation of Planets possessed docking facilties as large as Ur-Metheisn as they preferred smaller shipyards that were more spread out among their colonies. This was due to the Rihannsu train of thought that favored larger central structures. (TOS novel: Swordhunt)
