Remant is actually a giant transforming mech created by an ancient alien civilization, hence the name. The moon also transforms into a giant sword-whip-gun, appropriately named Vengeance, that all Hunters and Huntresses on the planet will have to use in order to fight a planet-sized ancient eldritch Grimm god, which wiped out the aliens, in a battle to determine the fate of the universe.
