Beasts with psychic powers and high intelligence, they have adapted to the way of the White World by abandoning their feral instincts. They have gained the ability to manifest their psychic powers, they're clad in armor covered in semi-transparent flames, some can fire psychic projectiles like magic, but they all vary in appearance and nature based on the creature. Are friendly deals with them based on their moods and laws of nature......? But if there is a threatening enemy, there is no doubt that they'll be a priceless ally.
