Mithras is a former lone wolf accepted into the pack after he was discovered on the borders with a horrible injury. After his recovery, he exists on the outskirts of the pack, not closely associated with any of the other wolves.
He's somewhat conceited and bitter, perhaps a side effect of the difficulties he faced living alone. Nonetheless, he works hard as a hunter and Arthul tolerates his presence. The pups are impressed by his stories and his scars, and he's one of the only adults that Octavian truly seems to respect.
For some time now, he's been eyeing the leader of the pack, and a challenge for the position may not be far off.
The formerly conceited wolf was switched to Tavia's hunting party after Icara's departure. His humble demeanor could be just a shows a true change of heart, and he became a more integrated member of the pack following this incident. Growing closer to Cotia through hunting, he eventually mated with the sweet wolf, and remained a dedicated partner and father for their many children.
