StarShipUSSKEhleyr German language Silver Age Star Trek. Set in an alternative universe in 2407. They were kind enough to describe it to me in English as follows:
In 2407, our story takes place in a universe parallel to the canon universe of DS9 with a different political power structure. While Klingons and Cardassians are allies of the humans ("Union of Planets"), Vulcans and Romulans never got separated and together with the Andorians form the hostile T'Khasi alliance. What we refer to as "mirror universe" is actually the canon mirror universe from DS9/TOS/ENT. Therefore, our black K'ehleyr uniforms deviate from the canon as well as the name of our ship. In contrast, for the mirror universe we have two groups: First, the "next terran empire", with uniforms that have similar features like the mirror uniforms of TOS/ENT, i.e. blue standing for science and red being operations. Second, the mirror rebels, which do not wear uniforms, like it is the case for the mirrored DS9.
