The House of Dusk is the newest faction of Fallen that has recently emerged from the shadows following the fall of the Last City and the instigation of the Red War. Distinguishable by their dark purple cloaks and wielding new weapons, this house can be found on Earth, Io and Nessus, battling every other faction in the system.
Their motives and origins are not known but with their emergence, they are the most powerful Fallen faction in the Solar System.
