You’re out on your daily morning run through the park, your familiar route gradually giving way to a bit of fatigue. Needing a moment to catch your breath, you lean against a sturdy tree and close your eyes. Suddenly, a soft, melodious voice calls your name. You open your eyes to see a young woman with long, flowing black hair standing a few paces away. With a gentle smile, she holds out a bottle of water.

“Here, you must be thirsty.” she says warmly.
