The Thennanin are an incredibly alien (and highly telepathic) race who are unable to communicate with 99% of other species, except through math and pictures (when they bother to try). Their civilization is highly advanced, especially in star drives and the biosciences. They are also a very hostile race that have conquered many neighboring alien species and destroyed several others, including the ancient Castax Imperium and the aggressive Primisaurr Empire. When encountering a race that effectively resists their expansion into space, the Thenannin usually dust the planet infested with the alien species with bioagents, wiping them out. They are a grim conquering force that also despise the Atorian Empire and are preparing for a major conflict with them.
