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. It's a spacious dining room, with open doorways leading to leading to a game room and a library off in the distance.
A large table set for dinner is in the middle of the room, with candles and plates, but without any food on it.
You can:
examine the table,
head to the game room, or
retire to the library.
