Enemies have their heads popped off, light spews out. Sword of Crota is "dark" We wield it with ease. Psions have abilities similar to ours, that we got from the Traveler Various Grimoire Cards We dont't even know what the Traveler actually does, or what its purpose or motive is. Traveler came to Earth even though it knew the darkness was following it, so it didn't care about us, it wanted to be protected. Therefore we're given powers and advancement in technology. Some enemies say, "It's the Darkness!" When you get close to them. The Speaker is shady af We're an undead army, risen without purpose Only purpose is to fight the "Darkness" The Darkness is whatever the Traveler considers evil, but may not necessarily be evil
