Mephil Trantos was an Orion base that existed in the 24th century. It was constructed from starship fragments, old space station parts and other components. The base was headed by Kestralnamen and had several dining establishments and gambling facilities. Bo'tex knew two Pandrilite twin sisters who had a stage show on Mephil Trantos. (TNG - The Captain's Table novel: Dujonian's Hoard) The two Pandrilites were likely Arrenya and Tensata.
