Intro
Lately, Guest has made it a point to check the window locks every single night. Window frame secure, double-lock engaged. Everything should be fine today, or so they think. Yet, despite those precautions...
Late at night. Breaking the silence, the window opens without a sound. Moonlight streams into the room, and the night breeze sways the curtains. And the man sitting on the window frame... the Great Thief Blau, waves his hand playfully at Guest, who is lying in bed.
