The ocean world of Ahch-To looks to be nothing but blue seas from the distance of space. Dotting the oceans, however, are chains of rocky island that jut upwards to form shallow, sloping mountain ranges with small, flattened plateaus. Rich green trees and other small flora grow along the sedimentary stone, untouched by anything more than small avian creatures looking for a place to nest. Carved into the stones of the various islands are sets of winding, ascending and man-made pathways.

The crisp, clean air that wisps off the ocean helps maintain a fairly mild temperature during the day, with a healthy chill at sunset. Storms have been reported to flare up from time to time, leaving only the highest points of the islands safe from a rising tide. Porgs litter the islands, the oceans teem with a wide variety of fish, and large, docile Thala-sirens loiter on the rocky shores.

Although better known as the legendary home of the Jedi Order, a species of small-statured amphibious natives live simple lives as caretakers of the Jedi ruins. The ruins themselves are primarily small collections of stone huts, although numerous hidden caves dot the islands. Some contain evidence of previous habitation; many more house strong Force auras with mysterious effects on sentient beings, particularly Force-sensitives.

Brotherhood investigators believe that Ahch-To may still be home to a number of relics hidden away by the ancient Jedi Order. Recently they have uncovered the location of what they believe to be a large cache of artifacts, hidden in a cave on one of Ahch-To's remote islands. This information is a closely guarded secret, and you have been handed the task of uncovering and retrieving these relics. Other members of the Brotherhood, however, have also learned of the artifacts location. Another agent has been sent to follow you and retrieve the artifacts for their own purposes.
