The Kran were a religious order that worshipped death by spreading destruction during the night. After the Kran arrived on the world of Dinutu during the Clone Wars, Jedi Master Mace Windu had them sent to a binary star system so they could live out their religion on hospitable planet where night never fell.[1]
