From what Minos had learned with Elen, of the three princes of this kingdom, in addition to Charles, the other two were named Wilfred and Blake.
Wilfred Walker was the first prince, 27-years-old, with a Black talent, and was already at level 48. He was the strongest of the three and had the support of his mother, the Queen of the Kingdom of the Waves.
Blake Walker was the middle son of King Walker, the son of one of the king's 30 wives, a woman from the prominent Woods family. And besides having the obvious support of that family, the second prince had already reached level 47, with his 25-years-old and Black talent.
Finally, Charles Walker, the enemy of Peter, was the son of the 2nd wife of King Walker, being the grandson of the current patriarch of the Collins family, a noble house of this state. Furthermore, he had already reached level 47, with his 22-years-old and Black talent. Therefore, he was the fastest in terms of cultivation of the three princes.
