Nava Ren
A little over two meters tall with broad shoulders but disproportionately lanky arms, Nava Ren tries to keep a clean, formal appearance as to avoid association with the stereotypes of both the aggressive Axanari and the uncouth lower Caste.  His electric blue hair is worn long but kept in a tight braid and he keeps his mustache and goatee neatly maintained.  He is eager to provide anyone with assistance and examine any new or interesting thing he has not encountered before.  He has been accused of being a "bit of a magpie" (not without reason--he argues it is his job) and actively is working to break the habit of not saying "I don't know" or lacking qualifiers on how sure he is based on the facts at hand.
