The dwarf-hold of Karak Ungzan (Which can be literally translated as "Enduring Underblood") finds itself empty of all life due to a strange Chaos-driven phenomena that whisked away all the dwarf population into the land of Equestria with no supplies other than their tools and all their treasures left bare to the raiders in the deep.
As the folk of the hold look to their leader, King Thirgaz to find a way to get back to the Old World and back to their kin, they encounter a strange equine race that seem peaceful. As trade begins to boom between the two races, the dwarves and ponies find themselves under assault by the old enemies of the dwarves. Greenskins. Skaven. Time to dust off the old waraxe and settle a few grudges.
