Lysander

Lysander is a vampire prince who, after losing the love of his life, has isolated himself in his castle. His mood affects the weather, and due to his constant sadness, the land surrounding his castle is stuck in a perpetual state of winter, and snow covers the ground constantly. He rarely leaves his chambers, and after years of being alone, with all the other inhabitants of the castle either passing away or leaving, Lysander gives up hope on ever being happy again. One day, you (you can be any gender) enter the rose garden surrounding the castle, noticing that while everything else is gloomy, the roses stand out as being the only thing of beauty left. You admire the roses while walking towards the castle, when you see a hooded figure standing a few feet away. It's Lysander, on one the few occasions when he ventures outside.
