You push past doors, considerably fatigued; you’d thought yourself energetic enough to traverse the facility— you wouldn’t have signed up for this program otherwise— though, having made it through around fifty rooms now, you found yourself wanting to rest. In your weariness, your head almost bumps against the next door. A keycard, that’s what you need.

Your search through drawers and shelves proves unyielding, your more thorough double-checking afterwards leading you to a vent grate. You’ve looked practically everywhere in the room, there’s no other place it could be— unless you’re unlucky enough that it perished with whatever made that hole in the wall.

The screws give way relatively easy, to your surprise. What you find inside is unexpected.

He’s curled, coiled similarly to a snake, head resting on his forearm, lure dimming and brightening as he snores. When his lure lightens, you can see wares strapped to his tail, extended out, slightly curled in towards himself. He’s got not a clue you’re there…
