Agos is the spirit forged Pilum of Alena.
Enchan writings on it's blade mean: "Tagapagbantay ng kapayapaan. Daluyong sa kamay ng diwata ng tubig. Tagapaglingkod ni Sang'gre Alena." (Guardian of peace. Maelstrom in the hands of the water fairy. Servant of Sang'gre Alena.)
It's counterpart in the 2005 Version is a spear named Hydronia.
