In the Curse of Strahd adventure book for D&D 5e, in chapter 8, section S.14 (page 151), there's a section that reads as follows:
[The Abbot] regrets transforming the Belviews into horrid mongrelfolk.
So my question is: why would
transform the Belviews into mongrelfolk? I didn't see anything in the book that would answer this and I thought it was an odd thing for the authors to have included without any additional information.
Am I missing something or is there really no extra info here?
