Orcs mostly stayed in the depths, deeper even than the dwarves would delve. The dwarves stuck to their subterranean palaces and strongholds and the fey frolicked on the surface. Giants made their way into the mountains, finding the remote places to be to their liking. Some dwarves followed them there and the small numbers fight endlessly. Some orcs remained on the surface, seeking out the desolate and uninhabited corners of the wilds for their homes; places the fey and dwarves would not wish to live. So was a tenuous balance established.
