Murder Mystery Synopsis:

This year, the monsters of the International Monster Association will gather on Mount Immortality for the annual Monster Summit. This secret meeting will be held in the Cave of Misfortune, next to the Glop Lagoon. The monsters will discuss the past year’s success as well as plans for haunts, terrors, and scares for the upcoming year.

Grimoth Jones is rumored to be making an important announcement this year and will also acknowledge the members who are far exceeding what it means to be a monster. You’ve received your summons, and this is where your story begins.
