Seven unfortunate dwarves thought they had found the perfect spot for fun. Neighboring goblins, elves, dwarves, plenty of water, metal, and just a touch of evil. Within minutes, a single dwarf was killed by a goat, rose from the dead, and beat everyone to death with his pants before they could even get a decent tunnel dug for everyone to hide in. Their brave journey had been so short-lived, their names, and the name of their claimed lands, were quickly forgotten.
Another group of brave, but only slightly less unfortunate, dwarves embarked near those dangerous lands and founded "Gangtours the Scales of Hay." They formed a hasty axedwarf militia to defend themselves from the undead terrors, successfully slaughtering a zombified falcon which had attacked the war dogs and peasants. The food, booze, and seeds were all moved inside, safe from marauders. While the miners dug down into the safety of the ground, the rest set about the construction of simple walls and bridges for defense from lesser foes.
The two members of the militia and their war dogs were set upon by another undead falcon, this one far stronger and more dangerous than the last. The axedwarves and dogs fought bravely but were defeated. Several fell in the reaches of the evil biome to rise again and set about killing the turkeys and horses still outside. The remaining four dwarves, the miners and two peasants, walled themselves in with walls of rock salt.
Now would be trapped, but with sufficient seeds, soil, booze, and food to last them until the next expected migration wave. With grim determination, they turned their backs on the sunlight as the last wall fell into place, sealing the underground tunnel, and dug down. Down, deeper, and deeper into the safety of the dark underground, to await the day when they could replenish their numbers and strike back against their undead foes.
