tonight I had a dream that was a pre-greenscreen fantasy comedy. it followed traditionally evil fantasy races arranged into the classical elements (I think I saw some demons and elementals. it was pre-greenscreen, so it mostly relied on practical effects, close shots and dim lighting), making a stand against a feared and rarely seen dark-angelic-themed faction through innovations in dungeon-design. the protagonist was a human (creature of spirit), who had a scene where he proved himself by inventing underfloor heating to create a room that appeared to be in a hotter location than it actually was. I woke up during a dramatic reveal that he was getting corrupted by black tendrils in his blood.
