Genned a new world and didn't realize until I went to play it that I had genned a world in which ALL races had been supplanted by kobolds. The small map is dotted with kobold forest retreats, kobold villages, a kobold dark fortress, and kobold hillocks/fortresses. The history was genned until 125, but the legends records stop at the year 47. The kobolds didn't conquer the world so much as they simply came to reside in places and then outbred the residents. In adventure mode, only outsiders are available for every race, and animal people are completely unavailable. The last recorded historical event was from the year 47 (as I said) was a dragon overthrowing the last dwarven civilization. Cannot seem to find a single being of any other race, but apparently there are still dwarves somewhere, though on embark it says that the civ is "dead or dying."
I accept your challenge dwarf fortress.
