Character Details

Weight: 49kg


★ Full name: Astren Walker
★ Pseudonym / mononym: Astren (stylised as ASTREN)
★ Name meaning: Astren is derived from the Latin 'astra', translating to 'stars'.

★ Birthday: 25th of January, 2089
★ Nationality: Australian-British
★ Likes: Finding information, video games, socialising, astronomy
★ Dislikes: Failure, liars, being restricted, physical activity
★ Fears: His mistakes



Upon first glance, Astren is very blunt and deadpan; he is not afraid of sharing his opinion about anything, and is surprisingly also not afraid of others sharing their own thoughts. Prefers the company of people over solitude, but will withdraw himself the moment his flaws are acknowledged. He is very perceptive and analytical, although his emotions may get in the way of his thinking.



Having to decide between staying in Australia with his family or go abroad to continue pursuing his interests, it was Astren's two younger sisters that persuaded him to do what he loved; music. Even though he had little initial experience, he enjoyed the concept of honing his skills and heeded his siblings' words; he ultimately travelled to the other side of the world in order to start a new life with his music.
