The northern-most settled region of my homebrew world of Akrellin, Aeden is home to the races of men, halflings and dwarves. Aeden is a feudalist kindom ruled by the venerable Blackstones of Melphïne, it's capital fortress city.
Ravaged by the Feral Wars only three hundred years past, Aeden rallied about its large fortress cities after all its unfortified plains, forests and valleys were annihilated by the tread of demonic and bestial hoof.
Men of the westerlands and Men of the eastern draws are divided by the Arxenodryl mountain range: home to the northern clans of Dwarves, who kept themselves ensconced (but not impregnable) mountain fastnesses as the lands beyond their steppes burned during the Ferals.
Halflings of the northern and southern forests allied with the even more reclusive Gnomes, and some rumours hint at contact with the Fey of the Wilds to avoid destruction.
