Sungrave Hidden Tunnels

Ancient secret stone tunnels running through Sungrave mountain with symbol-activated doors, peepholes into facilities, and ice-slick floors in deeper sections.

In Iron Gold, the Sungrave Hidden Tunnels emerge as a labyrinthine network of ancient stone passages carved through the heart of Sungrave mountain, their symbol-activated doors and concealed peepholes transforming them into a vital artery for stealth and surveillance amid the escalating war on Mercury. These tunnels, with their treacherously ice-slick floors in deeper sections, allow characters to bypass fortified defenses and observe critical facilities undetected, shifting from mere historical curiosity to a strategic asset in the saga's power struggles. Their revelation underscores the enduring secrets of the old worlds, influencing infiltration tactics and escape routes as alliances fracture and new threats arise.
