It's beginning to look a lot like Chr—REVENGE—mas!
Christmas is a joyous holiday that happens only once a year. When parents pull out the creepy surveillance elf and use it to ensure good behaviour during this stressful time. However, this year the elf is sick of it! This year he seeks revenge against the "creator" of this spy toy and will not stop until he has destroyed them—and Christmas!
This mystery contains a deranged elf, hot apple hard cider, adorably delinquent children, the real Santa(?), a rapping priest, the most polarising Christmas songs, a gingerbread army and other assorted Christmas-themed minions as the wronged elf seeks blood!
Made for use with the Monster of the Week TTRPG created by Michael Sands and published by Evil Hat.
You can hear a version of this mystery played and run as a holiday one-shot on Redgate and Wolf's podcast.
