The Sentinel Division of the Geban Foundation of Engineering is the only notable division of the Foundation and was established in the imperial capital during the Era of Absolute Expansion, approximately three thousand years before Modern Geba. It incorporates Frost Sentinel lineages and emerged from imperial engineering foundations in collaboration with Frost Sentinel researchers in Ngorrhal, combining military and climate survival expertise to create durable weapons, gear, and vehicles.
Sentinel controls over thirty-five percent of planetary energy sources alongside Joxi Industrial Holdings. Together they dominate over seventy percent of all accessible energy on Geba. Although partnered in energy, Sentinel and Joxi compete directly in all other markets.
Sentinel produces durable, all-weather technology optimized for cold and extreme environments. It serves both military and civilian sectors through energy systems, modular weapons platforms, entertainment infrastructure, and long-range relay support. In the entertainment sector, Sentinel competes with Joxi by manufacturing massive relay hub screens, instruments, music systems, and vibration engines that allow entire fields to hear performances clearly. Sentinel systems integrate with Joxi devices, as the two are interdependent across energy, logistics, and consumer infrastructure.
In the modern era, Sentinel is one of only two manufactories, alongside Joxi, actively making attempts to work with various groups and push into the Uncharted. Sentinel has been the most consistent presence in frontier expansion efforts for years, and its personnel were active in regions like Inland Thazvaar and near-Uncharted zones throughout the modern era. The Solarn Contractor Registry lists Sentinel alongside Joxi as hiring at all tiers and all contract types, making both the primary entry points for any contractor seeking volume and variety.
