Yeah, I'll change it back to "Bonded to..."
Background: Victor was a mild-mannered young man who snuck into a museum after hours on a dare. He was drawn to a historical display of Viking history, where one of the shields was shining with a golden light. He reached out to touch the shield, and a crack of thunder signaled the appearance of a mighty valkyrie!
The beautiful warrior woman focused her imposing gaze upon Victor. "I sense a great potential within your soul. What is it you wish to do with your life, boy?" she asked.
In awe of the valkyrie, Victor replied, "I wish to be a mighty warrior, like you!"
"Then let it be so," the valkyrie replied. Thunder boomed again as a bolt of lightning struck Victor, and by the power of the gods, he was transformed! But, much to his surprise, the power had transformed him into a strong and beautiful woman of Viking ancestry!
"Eek!" the transformed woman cried. "When I said I wanted to be like you, I didn't mean it literally!" But the valkyrie was gone. In her place stood a curious cat. Victor felt an empathic link with the cat, and realized she a servant of the goddess Freya, and she was to serve as her spirit guide to help her understand and master her newfound abilities.
With the cat's guidance, Victor learned how to change back into his normal form (much to his relief). But his female form proved quite agile and strong. He honed his fighting skills, learning to battle with sword and shield. Now, he lives a double life. By day, he is mild-mannered Victor. But by night, he roams the streets, dealing out justice to the wicked as the enigmatic Shield Maiden!
