Hebeth
Hebeth lies on a distant planet far from Argent D'Nur. It was chosen at the dawn of the war with Hell as the site for the Trans-Dimensional Barrier, a colossal construct designed to halt demonic incursions. Once an interdimensional port facilitating off-world travel, Hebeth's barrier was built by Sentinel engineers as a defense mechanism powered by the planet's rich veins of Aetherium Crystals. Its hyper-phased lattice cores generate a quantum disruption field, severing Hell's ability to open portals into Argent D'Nur. The mined energy is channeled through antimatter conduits, beaming the field across dimensions to shield the entire dimension from invasion.
