Through more of my readings, I think I have a more solid world built with the relations of all the races. The world is about three times the size of Earth so there's a lot of ocean and a lot of land so there are dozens of continents throughout the world, but the main setting of this story takes place on a continent similar in size to Pangea with some differences. I tried using WorldAnvil to build my world, but I need to pay to access those tools and I am tight on money at the moment. So I plan to find another way to have my world visualized. But as for what I have learned recently, I have found that some of the monsters have very interesting backstories that tie into some of the dark aligned races like the Duergar, Dark Elves, Fire Giants, Hobgoblins, and a whole bunch more. One creature I found interesting is the Retriever. It's a construct built by the Dark Elves that goes into the Abyss and collects demons to bring back to the Material Plane for the Dark Elves to enslave or sacrifice. But it's CR (Challenge Rating) is a bit too high for my players to face so it's going to have to be a deterrent enemy for the moment until they can fight it. But that all depends on if they even encounter one in the first place or go to the land of the Dark Elves which Is a land void of light, a place where the sun only peaks through small cracks of the looming clouds overhead. No one knows why the sun cannot shine there, not even the natives. I shall continue my research of the monsters to creature cultures, traditions, and behaviors of all the kingdoms, empires, city-states, and the monsters that lurk within their borders
