Darker than sin, Kerrigan was born the unnamed son of prostitute. He spent the whole of his childhood neglected and hungry. As a youth, he survived by thievery and lies until the fateful day when he was chased into a haunted wood. There his presence was brought to the attention of Morgen Le Fey who brought him to Camelot and then crowned him Pendragon.
Now he serves no one but himself. Cold and merciless, his only goal is to rule the world of man. But sometimes, even the best laid plans often go awry. In the case of Kerrigan, his foil lies in the unassuming package of a little peasant who holds in her hands the fate of the entire world.
Kerrigan kidnapped Seren because she was destined to give birth to the next Penmerlin and Morgen wanted control of that child. Kerrigan ended up falling in love with Seren and fathering her child. They escaped Camelot and now live in Avalon.
