You enter the first floor of the challenge tower, not knowing what to expect. To your surprise, the thick steel doors slide open to reveal a massive glass dome full of tall trees and flowering bushes. As you step forwards into the room, a gust of wind sends a sprinkle of falling leaves into your face.

After awkwardly wandering through the undergrowth for what seems like several minutes, you eventually make your way into a small clearing, where smoke billowing from what appears to be a fog machine faintly covers a large, ornate stone table. Across the table from you sits a young girl; she doesn't look like she could be older than fourteen, but something about her - you can't quite put your finger on it - suggests to you that she might be far older than she appears.

Upon noticing you, she unleashes a wide, lopsided grin: "Surprised? You're going to be playing me first." She gestures, vaguely, to a tree stump in front of you. "The name's Sylvia, by the way. Don't worry, I won't go easy on you." She pulls a deck out of her leaf-covered coat, and the two of you begin to play.
