all 3 civlizations, gobling, human, and dwarf were living together in harmony
wierd..
normally caused by goblins kidnapping other civs children and raising them as goblins. in older versions there was this awesomely delightful thing where goblins, being smaller and reproducing less then some other races like elves/humans, would end up dying out but leaving all their forts populated with the races they had been kidnapping, who would wear iron and think they were goblins. i can recall one of my more amazing challenges in 40d was iron wearing elite elven weaponmasters leading goblin sieges. all that elf speed combined with goblin forged iron plate was pretty badass. they actually scored kills on my adamantium clad chapions in my arena.
in the latest version ive encountered dark towers populated only by humans wearing goblin gear, and still kidnapping human children from the nearby towns, so i guess it still happens even with the goblin size increase.
you could also get goblins showing up to trade with you if you were somehow at peace with them, although having one as a liason sounds interesting if they were liasing for the humans or something. if you can check out the legends on that it would be really interesting.
also, the gremlin law giver sounds amazing. i didnt know they could even enter a civilization. find his story in legends and tell us about it. hopefully its as good as that elf who had his wife eaten by other elves, and rose to become the dwarven ruler through the terrible vengeance he wrought against his own pointy eared race.
ive yet to hear of a kobold leader of another race though. does that ever happen?
