Fiction:Traversian Reircha

The Transversian Reircha (aka Transverisan Democratic Republic), is an ancient ~6.4 Billion Year old Empire originating from another universe approximately 2 Billion years older than this one. The other universe was destroyed by the Transversians (Archridos) in order to prevent a parasitic/disease (The Dark Select) from spreading across their universe to ours. They built the ultimate doomsday weapon, and managed to escape from their universe, in their only surviving Ark, the Viria. They managed to get to our universe, but in the process, the Viria lost all transuniverse, intergalactic, and interstellar travelling capability, and was forced to crash land on a small planet capable of supporting the Archridos.
