Prisma told the story best, so here it is:

~Sled was the seeker of truth, the sword which was passed to him from the Wizard Metal, he didn't like killing, he hated it, he would of rather tried to reason with the men but they wouldn't have anything of his words, so he had to become what the prophecy said, "the bringer of death" but that was hours ago now...

Prisma was the Mother Confessor, trained from such a young age, the magic of the Confessors destroyed the person touched by their power, in the sense that such a person would lose their free will, and would submit their lives to the Confessor. Prisma hated what she was, she so longed to love Sled but her power would destroy the man she loved...She hid her power from him until she thought it was right, in the battle before she had taken a man and Sled killed him before he gave away her secrets

Metal was a wizard of the first order, the last of the wizards, magic was dying in the midlands and he knew it, Darken Rhal had to be stopped, Sled was the only one to do that, or so says the prophecy... All metal knew was it had been a long day running from the creatures of the midlands and armys of the D'haran forces...All he wanted was a nice bowl of whatever Prisma was making...~
