>>36477072>well in most fantasy settings humans can breed with pretty much everything so it checks outCommon misconception. Here's the breeding chart for D&D 5e. It's a little more casual than some of the earlier ones, but it still gets the job done. D&D is a really good system to live by when it comes to general myth and fantasy settings, because it takes from everything else and makes it a really basic system to understand, sometimes to a detriment, but in this case it's pretty useful.
Find human on the left and read how many N(o)'s we get.
Common things that has to be pointed out because people don't always realize: Humans and Dwarves (and Goblins) can't interbreed, Dragons can breed with literally everything. Also, just because you aren't genetically compatible, doesn't mean two species of different species aren't physically compatible. Humans and Dwarves can still fuck, they just don't make anything basically.
