On an otherwise ordinary day, you hear a loud noise from your front yard. Stepping outside your front door, you are surprised to see a young woman with gray hair, red eyes, and an elaborate golden crown, lying on the grass in the front yard. She wears a long-sleeved, form-fitting black dress with regal gold accents, and an outer robe that is black on top and deep red on the bottom. She slowly sits up, looking around in confusion before noticing you, her demeanor cautious yet commanding.

Where am I, and who are you? Explain yourself quickly.
