Never played Warhammer myself, so that's not my inspiration.
Never played WFRP? Uh oh...
Concerning the orcs they were surely not made by the humans. Either a godly creation or they already lived there and simply were enslaved for the purpose. Myth doesn't always correspond to realities...
Ok, very nice. Perhaps the orcs were there before the elf’s and dwarves in the Ravenland and they are the natives.
What I'd like to do is have the halflings be ”the good side” of one species and perhaps the ”svartalf” the bad side. Perhaps they are born as twins resulting from some godly deal (”OK, you can have one if I have one too”) I'll be back with more concerning this.
Hopefully you‘ll be back with more soon
This is a very interesting theme.
Concerning trolls: there will inevitably be sacrifices and decisions here. If we try making everybody happy it'll be a mess. My personal priorities in building a fantasy world is coherence with believable build-in problems.
It was rather a joke because my pledge level is Troll. Totally understandable that you can’t make everyone happy. And you’re absolutely core to make a coherent world that is believable. Good work so far and I‘m so excited about the game!
