The Fierce Ones are the ones who oppose Opalheart and his kind, Prismshard's children. They want to get rid of the existence of the Whinok Children and get their abilities, like immortality, to rule their kingdom and world. They think everything, from a speck of dirt to the great Opalheart himself, has done bad to them, and they are hungry for revenge. Prismshard is their king, and he will stop at nothing to get revenge for not being king. He wants his father to be the past never explained, and he wants to take his place instead. The Sky amulet has his presence in it, and whomever has it on could hear him and his evil deeds. Since he is so strong, he is able to take over the body of the wearer. That is how his children know about him, and they will kill all of the Whinok Children. It is said that if they get a certain amount of blood from all eleven of them, and crack the Sky Amulet, Prismshard will be alive once more and take his father's place, King of all.
