Yelmalio was a commander and leader. He met and fought many beings for the cause of his father in the Gods War. But at the Hill of Gold he was disarmed by Orlanth, and then he was ambushed by Zorak Zoran, who stole his fire powers. The Son of the Sun fell and bled out his life-giving heat. His favored weapons of bow and sword fell also, and were absorbed into the knowledge of the whole world.

During the Darkness Yelmalio's wounds did not deter his struggle. He joined with the Lord Elf and others to fight against the relentless approach of chaos. He survived, and greeted the rise of his father, the Sun, at the start of Time.

Since that time, Yelmalio has lived in the mountains and hills, and even the staunchest Orlanth worshipper admits the presence of the Sun.
