This is a character and a species of dragon created for the book Sanyahona. It's an old drawing, by the way,
with some modern touches. He is a reptilian anthro, more feral than anthro, who does not possess wings. Being larger and heavier, they cannot fly.

Earth dragons are fierce and honorable warriors. Richard, the human protagonist, gains his trust by healing his wounds after a cowardly ambush. Some time later, Bondoresek returns the favor by saving his life from other dragons who want to dine on human flesh.
