Sena was a Greek archer and the most skilled marksman of the group he fought with. He fought along with Denisen, Demicres, Lenna, and Chale during the Setonian War. After the Setonian War, he left with the others to go to the Norselands to help their new found allies in what was thought to have been a small dispute. Shortly after their arrival, the Ragnarök occurred. He fought bravely during this time. But, he sacrificed his life to save both Denisen and Chale from an enormous Mountain Giant. After his death and the Ragnarök, Denisen brought the brave archer to fame through his story, Trials of a Greek Soldier.
