1486 A.D. – Fresh from his treacherous turning of the tides against Richard III in the Battle of Bosworth, Sir Gaston de Russe’s reputation is dark and dirty. Those loyal to Richard hate him and those loyal to Henry Tudor fear him. He is, after all, The Dark One. In order to gain a strong foothold in Yorkshire, Henry sends Gaston to one of the largest fortresses in the north, a massive bastion called Mt. Holyoak Castle. Having formerly belonged to Sir Guy Stoneley, who is now a prisoner in the White Tower after his capture at Bosworth, the castle is still the home to Guy’s wife, Remington, her three sisters, and her son.
