Belonging to the lowest rank of angels, compassion is said to have been a sacred weapon brought to the celestial plane after the hero it traveled with came to the end of a long journey.      Charged with protecting the celestial gates, its powerful drill deals swift justice to anyone who carelessly trespasses into the divine realm, often leading a flock of cachets as it does so. This same drill also enables it to burrow beneath the ground, to take its foes by surprise.
