ASOIAF/GOT The Dreadfort is turned into the Breadfort, House Bolton's flaying knives are turned into baking instruments, Flayed Man is now the Fat Man

[CarlManvers2019]

This change occurs around 5 years before the start of canon

No one can explain HOW the Dreadfort is made of edible yet warm and durable bread

Roose Bolton himself cannot explain why he has these "solar hands" or why he now likes baking bread

Or why/how reality seems to bend whenever people eat bread
