The rat farms are a set of underground complexes beneath Castle __________. They were used to house and feed the rats, though their feeble fences did little to keep the rats contained. It was hinted, and eventually confirmed, that the rats were fed bits of their own kind. The rat farms are adjacent to ledger rooms where Dragomir once hid his diary; these rooms have since been revealed to contain foulfungus spores.

Because rats have been banished from Castle __________, the rat farms have been refurbished into the guinea pig farms. Aside from the change of animal, the difference is fairly negligible.
