Graviheer

A paradise city on the back of a gargantuan sea turtle that roams the Sea of Swords. Its waves announce its arrival from miles away. Split into an eastern part (General Taylor's domain, with the welcome docks, Waikiki, the tavern Mia Bella Signorina, and the infirmary) and a western part (the dwarf blacksmiths and the old enchantable-stone mines). The party discovered it is not reachable by normal seafare — Terrania realised their coordinates jumped from the far south to the far north between voyages.
