Book doesn't quite pick up on the Doctor's tone, he just keeps smiling patiently. "There doesn't seem to be an overarching reason, as of yet. There have certainly been a lot of strange occurrences. No statues, but not too long ago, for example, everyone fell asleep at once, and we seemed to be falling into each other's dreams. I've also heard mention of an incident where a number of people on board were turned into horses."

"Not all of it has been benign, though, apparently there was also an attack, by things that people here described as zombies. Sounded a lot more like Reavers, from my world." Book frowns, and shakes his head to dispel that thought.

"A few people on board have theories, though. Gryf runs this place, but she doesn't know how we're getting here. Shipmaster 'Vadum would also likely be helpful to talk to, he's been here for quite a long time. Or, you could try talking to the Doctor. His explanations aren't always the most clear, though."
