Built on the towering heights on the Eastern end of Harbor Island, Tump 12 has a wide field of fire bearing on the Eastern approaches of the Channel Forts across the Dargonesti Narrows.
Third from the Shay Head side, IN#12 also secures the Eastern fortifications on Harbor Island, which connect it to IN#11. IN#12 mounts more heavy artillery than any other single tump, because of its fields of fire.
