The Exodites are members of the Aeldari species that rejected the slow degeneration of their ancient civilization in the Warhammer 40k Universe.
To avoid the coming cataclysim, the Exodites exiled themselves from the core homeworlds of their star-spanning empire to newly-terraformed colony planets called Maiden Worlds. Upon their new homes, these so-called "Exodites" could isolate themselves from the Aeldari's brewing corruption and hedonism, and survive the cataclysm that would soon consume their people.
