My Santee for this year's installment of CtC Discord Secret Santa happened to be Rook, who I knew as a very good fellow pencil puzzle setter, as well as someone whose tastes aligned very well with my own. This lucky assignment gave me the inspiration to put my genre-bending hat on and go on a little mission. Let me just say that none of the three alotted weeks went to waste while preparing this gift.☺This was my first "real puzzle project", and the proudest one so far.
I'm going to post the resulting nine puzzles (alliterating CHRISTMAS) in three installments of three. The difficulty should be more or less consistent across the board, with some intended outliers on the harder side.
Huge thanks to Stef Liew and Prasanna Seshardi for immense help with testing and feedback!
