The Eternals is an alien race of sentient being that consist of star or cosmic energy. They are worshiped as the god by the majority of people in Gig. Eternals appeared in these lands with the fall of the Heart Star, which later become the Star City.
Eternal Emperor and Empress are rulers of the Empire and are worshiped by priests of House Aurion. The Eternal Magician is embraced by sorcerers of House Devaedra. Some Eternals help mortals (like the Knight within House Karakesh), some of them wander the world in disguise (like the Hermit) or just challenge its residents (like the Seer).
