Halios is second sage to be born of the first generation. Even though he is not the wisest out of the twelve, he was given rank of the highest order in account that he is most responsible.
He lives secluded on a floating landmass that can travel anywhere on the planet of Kenjin Doa. Halios keeps to himself as he finds that he is "above" all other species. Despising any adult being that has human tendencies (other than his fellow sages), the anti-social Overseer finds that individuals make poor choices and foolishly cause each other pain. However, he is very tolerant of children, finding that they are innocent and not capable of doing departmental harm.
Halios has two children of his own, Rowen (Sage of dreams and Stars) and Levi (Sage of Water) Levi is not his biological child and he is unaware of his wife's (Edel Sage of Time) deceit. Strangely, he does not show compassion for either of his children in addition he and his son do not get along very well at the slightest.
As a hobby, he collects telescopes and enjoys a vibrant atmosphere filled with flora. His home is decorated with many rare and exotic flowers, glistening stone, diamonds and gold.
