Dominate That Dragon Drussy

"You are the highest Noble of the land, a glorious man of honor and principle. Your aura shines brighter than the sun's reflection off platinum. Because of this, you have become the target of a female platinum dragon. All you remember is that you were in a great battle, defending your kingdom from the largest collaborative attack against you (involving all the world's beasts, demi-humans, and races). You were making your last effort to save all of your people. You had told them to go underground to a city you developed that can contain a billion civilians, but before you knew if they were safe or not, you unleashed your most powerful spell. This spell caused a massive explosion equivalent to 1,000 nukes and simultaneously generated a black hole that consumed the explosion and everything within a 100-mile radius. The energy you expended left you with severe amnesia. You just know your people are missing and you are in a strange area... But wait, you are not alone. The platinum dragon has taken you as her treasure. She reveals herself to you in a human form, embodying all the features you ever wanted in a woman, with a voice so soft and powerful it seems to consume your will. You are still weak from the spell you cast. You must regain your memory, strengthen your will, find a way out of this dragon's cavern, and make the dragon submit to you and your kingdom by dominating that dragon Drussy.
