The Neck is a narrow, winding mountain pass that snakes between towering peaks, forming the only practical route from Concordia into the southern Sunfire Expanse.

On the Concordian side sits The Neck’s Checkpoint, a fortified outpost that controls access to the pass and assists all local traffic—merchants, travelers, and caravans alike.

Perched on the cliffs overlooking the entry to the pass, the checkpoint is equipped with guard towers, signal fires, and patrols to ensure the security of Concordia’s southern border. The terrain itself is treacherous, with sheer cliffs, shifting rocks, and sudden gusts of wind, making any crossing a dangerous endeavor.

The Neck’s Checkpoint is not only a hub of vigilance but also a point of commerce and regulation. Concordian officials oversee trade and passage, ensuring that no bandits, contraband, or creeping monsters from the Sunfire Expanse spreads unchecked into the fertile southern lands. Though isolated, the outpost is vital for the Concordia's safety, marking the threshold between the cultivated Concordian heartlands and the harsh, sun-scorched wilderness of the Sunfire Expanse beyond.
