As you walk toward it, the door behind you slams shut, blowing out your candle, and startling you enough to drop it. You grope for the door in front of you, reaching the handle, and falling into a dining room with a thud. That door slams behind you and locks.
Fortunately, you're in a well-lit room. Unfortunately, you can't find your knife.

You look around. In front of you is a table with food being served and consumed without any visible sign of people holding the utensils, moving the plates, or eating the food. Candles, plates, floating knives, and a sense that you're not alone pervade.

Open doorways leading to a game room and a library.
You can:
approach the table,
watch the feast from a distance,
head to the game room, or
retire to the library.
