 	"You enter what appears to be a guest bedroom. The bed is made. The candles are lit. A man sits on the edge of the bed with his back to you, perfectly still. He has been perfectly still for a long time. When he turns, only his head turns, and TwinBee notes the impossible angle and files this under 'revenant — directed undead, single purpose, finite lifespan, very patient.' The patience is the part that worries TwinBee.",
 	"The hallway dead-ends in a chapel. There is a kneeling figure at the altar. The candles around him are unlit but somehow casting shadows. He has been praying since before the manor was haunted, and the prayer was not a request — it was a contract. TwinBee says: 'Revenant. The contract is the encounter. Break the contract, end the fight.'",
 	"A library. The man at the table is reading a book that has no pages. He is reading it carefully. He looks up when you enter and his expression does something that suggests he was expecting a different visitor and is willing to make do. TwinBee notes the revenant's hands — the bones in the wrong places, the joints set with intent — and recommends ranged engagement until the geometry of the threat is clear.",
-	"The ballroom is empty except for one figure standing in the exact center, not dancing, not waiting, simply standing. The chandeliers above him are not moving. They should be moving — they were moving in the last room — and the fact that they have stopped where this figure is standing tells TwinBee everything TwinBee needed to know. 'Revenant in the middle of a stilled room,' TwinBee says. 'He brought the silence with him.'",

TwinBee notes the revenant's grip on the cradle's edge and suggests, quietly, that whatever happened in this room is not the encounter — the encounter is what walks out of it.",
