Caladrius

This is Caladrius, an immortal hound-looking creature with a heart of gold. Named after the caladrius from Roman mythology, he has special healing capabilities. People have tried to use his powers for their own gain, but luckily Caladrius is no mere beast and has outwitted the evildoers attempting to control his life. Currently, he is the guard "dog" of a Hero-turned-shepherd, but as his human companion ages, Caladrius may soon need to head out into the world again.
