Aven Va Mori-Geis is described as being shorter than average, but with broad shoulders and a powerful build.  He has a round face, close cropped hair and dark skin.  His eyes are brown with a slight reddish tint, common to people from his birth place, the rural cay of Sevallin.  He is known for being intelligent, thoughtful and confident.

Aven is the second most senior agent working at the Aleph Association's Arkebis chapter.  Due to his thoughtful nature, many seek his advice on both professional and personal issues.

Aven often finds himself in the role of negotiator, mediating disputes between Aleph members.  Though he excels in this role, he has not forgotten his combat training and is considered to be an expert swordsman.

Aven came to the Aleph in his late twenties, already a skilled attunweiyld.  Some wonder where he acquired his skills.
