Teleportation grid

The Teleportation Grid is a device invented by the Forerunner.

Halo was built with an extensive teleportation grid that covers the entire ring. It is unknown exactly how the grid digitalizes matter and transports it, but it is theorized that it may be simply a miniature, and more precise version of slip space technology, in that it transports matter in the same way UNSC and Covenant spacecraft travel through the galaxy. The grid is powered by a series of superconducting cables meshing through the body of the halo.

The teleportation grid does not seem to suffer from Relativistic Lag.



Halo: Combat Evolved
The Teleportation system was first seen in use by the Monitor. The Monitor, having met up with Master Chief on the top of a building, teleports him to the Library, so he may retrieve the index. Cortana later taps into this same network, using Master Chief's MJOLNIR fusion reactor to power the teleportations.

Halo 2
It at first seemed that only 343 Guilty Spark, and marauding AIs (such as Cortana had access to such an instrument, but it was soon found that Gravemind was also able to use it, possibly through possession of 2401 Penitent Tangent, the Monitor of Installation 05. Because Gravemind does not transport himself or other Flood through the grid, it is probable that the grid has fail-safes, such as verifying non-Flood genetic material, in order to prevent the spread of Flood via teleportation as a variable transportation.
