Simeon is the leader of the Giddy Nine. Everybody in the group obeyed his every command. He was described by the Blind King as adventurous, more of a soldier than a minstrel. Thus, he used the Giddy Nine's music as a subversive tool, and the group began to make enemies.
To solve his problems, he visited a prophetess who told him that if he floated off a waterfall, a hero would be summoned. She did not necessarily mean that they had to give their lives in the process, but with the exception of Tark, that is what happened. Fortunately, their sacrifice was not entirely in vain, for Jason Walker came to Lyrian when he heard their music coming through a portal.
