This short one/two session FIST scenario is memorable, expandable, modifiable, easily internalized/memorized, and features a fun threat of the "potential -TPK but not world ending" variety. Which is the ideal level of danger, as it has givable stakes and may leave PCs defeated and scarred but not removed from play. In short, it checks all the boxes for a one off scenario within a campaign.
The monster is conceptually similar to Raggi's example of how to write a monster from the Lamentations of the Flame Princess GM/ Referee guide, only scaled to heroic adventure instead of the LotFP / OSR "life hates you, suffering is your lot, you die in a hole, now roll a new character" philosophy.
Good for FIST. Or, with mild tweaking, Dungeon World. Or a GLOG-like. Or Pulp Cthulhu.
