Cyrrhenic Empire
From Tardis Wiki, the free Doctor Who reference
The Cyrrhenic Empire, also known as the Cyrrhenic Alliance, was a group of aligned planets, including Levithia.
The Empire had fought in the Alliance Wars (or frontier wars), such as on Freytus, most led by the emperor Graff Vynda-K. Despite this, they refused to back him on the throne after his half-brother took control of his planet. (TV: The Ribos Operation)
