Invasion of the Infernal Host

Era beginning/end

As the boundaries between the planes thinned, the armies of the evil aligned outer planes staged a massive invasion of Zheng-Kitar as portals to those realms opened up all across the northernmost icy reaches of the Shenchuan Tundra, pouring out legions upon legions of devils, demons, daemons, and more that would organize and head south - eventually slamming into the Dwarves of Nan-Durghalihr, who would be given the unfortunate task of handling the war all on their lonesome while the rest of the world looked on in terror.
