Fanged Funnel is a 34 page level 0 adventure for Shadowdark RPG.

  In corrosive corridors, a caustic Queen is concealed                                                                               She spans sum surface sulfuric, a seething cosmic clot congealing                                                     To collect her incomprehensible, curated kingdom of corruptions.                                                                    
The scenario is set in the Malic Mindshaft: a liturgical slave colony burrowing inside the mind of the Hermit Queen. Your tunnelers believe the subterranean mine is reality, yet their bodies hang inverted elsewhere, slumbering in organic coffins across the overworld.

The only way out is to play along with the job system, survive the waves of acid creature attack, and uncover what is really happening.
