This was made long ago, i'm not sure if i had this up or not, but meh. so here a little back story to what's going on here.
Malefor pretty much raped Brandon's mother (He went by Greydor to escape him years later) and when she died when he went to take the eggs and found that his egg was from the female he raped. Taking the egg and raising him in secret he taught him all he would teach for fear he may over power him. Telling his son that it was Spyro who killed his mother, and on the day he went out to kill Spyro for the death of his mother, he met her in a dream. His mother told him all of what Malefor was doing and then as a way for him to forget everything, she telaported him to the village she grew up, and wiped his memory clean.
Years later Malefor found him, and Told Brandon (Who went by Greydor) who he was and who Malefor was.
