Way down south, at the swampy edge of the bad lands, there's a runty mountain. This mountains is full of the lowest dirtiest and smelliest cave goblins you've ever seen. These boys have hidden in the mountain for years, not making a peep. Sometimes they crept around the swamps at night to catch frogs, but mostly they kept to themselves growing shrooms and squigs for food and trade.
Now no one knows what happened but them Muckers have found the fight! Rumor has it the they found some special mushrooms growing in the squig drops that are very very potent indeed. Now they think their hard as they come and is riding all around stealing and pillaging and bringing it all back to that little runty mountain of theirs. I guess it'll never end until they's all dead or they run out of weird mushrooms.
