The Orassans Mod adds a space cats faction. They like the cold. They hail from a planet that could be described as an arctic nightmare to humans, but it is nice and cozy to the cold-loving cat people. After developing artificial wormhole generation they have decided to unite their home planet and expand their empire at an unprecedented speed. While generally friendly, they will not tolerate kidnapping their people and they may be upset due to you encroaching on their territory.
You can start as an Orassan Enclave by setting the colony type in the scenario editor.
