Kalretia (or, more formally, the Kalretian Archipelago) is located to the northeast of the Tirin Peninsula. Its thirteen islands have approximately the same total area as Ta'Araen.
The true natives of the islands are apsuri and lizardfolk. But in recent generations, humans from a northern continent have established a colony on the largest island. As a result, two distinct major cultures have sprung up: "Islanders," centered around the main seaport on the largest island, are primarily influenced by the human colonists; "swampers," denizens of the brackish swamps of the northeastern islands, are primarily influenced by the apsuri.
