The Legends of Ravnica,
This human man looks to be in his late 40s to early 50s, but is powerfully built. His skin is deeply tanned, even upon his balding head, from many, many years of patrolling the streets of the city. He wears a breastplate engraved with a cross and a set of wings, the Boros signet design. His greatsword doesn’t leave it’s sheath unless he is ready to take someone down.
Koss looks like an old badass, and in this case looks are NOT deceiving. Though he looks (and is) tough, he is also fair. He keeps the rules, but keeps the rules in check as well.
