Mollusca Tullie

"Never in one place at a time Mollusca Tullie is actually a small settlement of nomadic halflings built on the back of a giant snail. They defend the snail with their mastiff cavalry and in exchange, the snail provides its shell as a shelter. The settlement moves from town to town peddling its wares but often it can be found at the fringes of civilization or in transport to another nation. The halflings say they do not permit passengers but they often bend this rule for the right price or some item of use."
