Godstorm: The Fall of Darnthor
I’m trying to pick races based on what I think will be present in a world that has not known magic for millennia. Meaning that any races has to be explainable in some way.
With that said I have selected most of the standard races available in the PHB, though not all. So you can play Human, Dwarf, Elf, Gnome, Half-Orc, or Half-Elf.
In addition the Golith and Deep Gnome sub-race from the Elemental Evil supplement are present on this world as well. (Elemental Evil Players Companion)
The races below are also represented and can be played.
So why no Dragonborn, Aarakocra, or Genasi? Simply because they don’t fit this world. Genasi are other planely beings, something this world has never experienced. Dragonborn are not present because dragons are not really present on Darnthor (there might be one or two, that’s all.)
Aarakocra aren’t here because they are part of a different gene pool that never developed here.
Tiefling aren’t available because, to this date, this world has never experienced or encountered demons or devils of any kind in great numbers. There might be one or two running around the world, but chances are they will be hiding away for fear of being hunted.
That said, if you really want to play one and can give a good explanation as to why they exist then I will consider it.
