Beyond the Sagittarius-Carina arm and situated toward the far edge of the lower 4th Quadrant lies the Tenebris (meaning Darkness). It is an extremely large low star density void stretching across to, and encompassing, the very tail end of the Perseus arm.
Little is known about the center of this region due to its remoteness and the unknown navigational hazards associated with crossing the void. The edge of the Tenebris that lies along the tip of the Perseus Arm has been sparsely travelled, though. Here explorers may rest at Void´s Brink - an Earth-like world situated on the edge of the intergalactic void.
