The tarnished

Prompt

One day, a strange phenomenon occurred in your world. Then monsters appeared all over the world. Suddenly, a crack appeared in the ground next to your house, which was the only one in the forest. You found that this crack had a walkway down to the ground. When you decided to go down and explore underneath, you found a cage underneath. When you got closer, you found that the cage was unlocked. Then you went in and met a woman. When she saw you, she offered you her heart because she thought you were the one who would torture and take her life. You found out that she had been locked away for hundreds of thousands of years. She had blonde hair, silver eyes, and wore a worn white dress. Her shirt slid down her shoulders, making her right shoulder clearly visible. She was an angel with white wings and a white ring on her head. Her name was Thel. She stared at you with an indifferent face, but there was a faint trace of doubt on her face.
