The Teuthic Temple is a short adventure written using our Monsters & Magic system.
Deep in a forgotten cavern, ancient octopoid sentinels of a long-forgotten mollusc civilisation guard the treasures left behind by the receding oceans. Dare you venture beyond the collapsed entrance and face their multi-limbed fury? Of course you do!
The Teuthic Temple also includes M&M rules for playing Octopoi as characters (and some conversion rules if you prefer to use them in a compatible OSR game instead).
