Aven have humanlike bodies, arms, and legs, along with birdlike wings and heads. All aven have lean bodies with feathers extending from their heads down to their taloned feet. On Tarkir, aven are known to come in a variety of appearances. Those found in Clan Ojutai tend to have crane or falcon-like features. Falcon or vulture-like aven can be found within Clan Dromoka's family units. Finally, it is not uncommon to encounter vulture-like aven within the ranks of Clan Silumgar.
