Thuran really does not have any noticeable quirks.

While he is talkative, he always holds back on divulging too much information.  He does like poetry, however, as that was the most common medium of artistic expression out west.  He is also very found of telling lies, something he does a lot.  He is found of music, and if one of his companions decides to either sing or play an instrument he will try and find a way to join in.  

He also keeps an eye on everyone he travels with, his carefully trained eyes always looking for any signs of deceit or deception.  If he has a feeling that someone might have a plan to hurt himself or others in the group, he will find a way to remove the cancerous member.

He has a fascination with some things that Easterners consider mundane, such as the large crop fields or the bulky metal armor worn by soldiers.
