For those of you counting, that is 62 Goblins in the world (63 if site administrators aren't counted in the population counts.)
61 Technically, since I killed the one in Liedikes (Actually that town was pretty much depopulated. I had to avenge Boatsspiraled's defeat 350+ years ago by the Spider of Humidity, and so I killed the last goblin in the civ that took advantage of their defeat by building a Dark Fortress nearby, The Malice of Moons. The humans didn't appreciate it. I carry around his head still. The rest are rotting in their unholy temple. I'll probably go back and free the prisoners sooner or later...)
