Blood Knight

Too long had the war between the people of Roanoke and the dark magical cult that cursed them raged on. Armies had rose up, and fallen, blood spilled in their leader’s names. Enter Amelia Hayes, destined to bring down the royal family of Roanoke and plummet the land into the depths of darkness. A tragic fate for an innocent unborn heir.

But a twist of fate insured this plan did not fully succeed. As the war waged on, the child was rescued by a passing Samaritan. He gave her a life free from darkness and pain. For all the evil she was destined to do, she chose to use her heritage for good. She became Blood Knight.
