The southwestern slopes of the Screech Peaks define Ios's northern boundary. The mountains provide natural defenses, mineral resources, and the headwaters of the Dipindre River. The passes through to Moigos are few and difficult, limiting contact between the states.
Todakres is built against these mountains, using their height for defense and their stone for construction. The upper reaches above the city are wild — home to the creatures that give the Screech Peaks their name.
