Substances are a good corner case. I had one of these in my campaign which had no mechanical properties - just a particular type of metal one of the NPCs wanted to acquire. I put it in a generic "setting element" category I'd made at the time, but that was way far back - like before the World Almanac existed. Since the sever was implemented, I think I just deleted the entry out of frustration ^^;

With the current category structure, and the emphasis on that structure being shared, I think it's neecessary to provide for materials/substances like that, as well. I wonder if e can think of a good term that encompasses both species and substances, but it still simple and informative? I'm off to thesaurus dive.

Come to think of it, my entire setting is named after a mineral that really should have its own topic entry.
