BONUS: The Revenge of the Janus Beast

In the Second Citadel's Hall of Trophies lie remnants of hundreds of monsters... and some of them are livelier than others. The head of the Janus Beast, for example: it's been here for weeks, and it's growing bored. Very bored. Can the Janus Beast's head break out of its case using nothing but its two faces, magic spells, and one tiny, tiny, little, really-just-impossibly-small brain? Welcome to the Penumbra, dear Traveler. We hope you enjoy your stay.
