The youngest of the four heirs to the throne of Altar, Zelus is a kind hearted being, always willing to help others. Popular with the population, he never wished to rule, but he allowed himself to be considered out of respect and love for his parents. When his sister, Nike, went missing he wanted to search for her. However, his elder siblings were not so willing, and they managed to convince the population that he was too inexperienced and naive to rule, so his position in line to the throne fell. Now he is second in line to the throne, since his sister Nike and his brother Kratos are no longer on Altar. But he still struggles against Bia's influence over his life.
