The only known conduit was located between the Forerunner Dreadnought in the center of the city and one of the towers on the city's edge. The conduit consisted of a beam of green energy projected from a station located in one of the towers. Individuals using the conduit would be lifted to the beam by stepping on a pedestal at the far end of a large platform overlooking the dome; upon accessing the conduit, they would be propelled to the beam's endpoint at extremely high speeds. The conduit beam was surrounded by a series of evenly spaced support rings. The final support ring closest to the Dreadnought was significantly larger than the others and had eight petal-like fins which were folded in when the conduit was active, but would open when the beam retracted. The support rings were apparently held in place by the conduit itself, as they would fall down once the beam was deactivated.
The only known instance of the conduit's use was to allow John-117 to enter the Forerunner Dreadnought at the conclusion of the Battle of High Charity. While Cortana managed to delay the Dreadnought's launch for a limited time, John-117 barely made it into the ship as the conduit closed.
