Quarry

In the South is a land dubbed "Quarry," which is a human kingdom that remains officially unaffiliated with any other group, including other humans. It’s true name is Gaela. Their main export is a rare clay found only on their land. The kingdom is shrouded in mystery and an impenetrable wall made of the same clay they export. Even the Quai sing the praises of Quarry's clay. No outsider has ever been beyond the walls, save for scouts and spies who never returned to report. They are friendly to all visitors, but all trade and hospitality is provided outside the walls in Rimtown where there are inns, taverns, and a rich market.
