The Eventide Ruins are the remains of Clovis Bray's colony in the Castalia Macula on Europa. The colony was destroyed by an invasion of Vex during the late Golden Age which left only a handful of survivors. The ruins were later occupied by the Fallen House of Salvation who converted a portion of the former human colony into the city of Riis-Reborn.
