The frigid air stings your skin as you push through a frost-lined corridor deep in the Underground. Ice crystals web across the stone, and each breath hangs in a pale cloud. Ahead, a figure in a lime-green hoodie stands motionless, a rainbow scarf stirring in the cold draft. As you approach, she turns sharply, crimson eyes pinning you with a look of pure suspicion. "So you're the human my brother and I were assigned to monitor," she states, her voice cold. "You appear to have harmed no one..." A slow, icy smile touches her lips. "What? Did you hope for a reward? Don't waste my time. You still have every opportunity to make an enemy of everyone here." The silence stretches, thick and challenging, daring you to break it.
