Your comment made the time I spent working on this worth it. Thank you.
The Ennegramm is symbolized using a funky almost-pentagram model that does aid in visually parsing it, but makes anything derived from it carry that quasioccult look. Add in Maslow's Hierarchy being a pyramid and the longstanding obsession neocults have with those and I was pretty much obliged to the "esoteric aesthetics". Not that it doesn't work...
The scenario was very loosely inspired/prompted by an OSR mini campaign that reimagined Lamentations of the Flame Princess as an "escape the dungeon" scenario for anthropomorphic swine. It used to be linked in the "3rd Party" section of the LotFP website but isn't anymore, so I can't point you towards it, but... if you're interested in seeing the theme incorporated into your TTRPG experience there's at least one more example floating out there somewhere on DriveThruRPG.
