Jericho-Maw Warp Gate

The Jericho-Maw Warp Gate is a Warp Gate of unknown Xenos origin that joins the former Imperial sector of the Jericho Reach in the Segmentum Ultima to the turbulent, Warp Storm-wracked region of space called "the Maw" that divides the Calixis Sector from the Koronus Expanse in the Segmentum Obscurus.

Any solid matter passing within the sweep of the crescent's great arms - which span a distance over a hundred kilometers - disappears into darkness and is hurled irresistibly to the other side of the gate and spat out, arriving on the other side of the galaxy.

As far as can be discerned, the time taken by the transit is all but negligible; mere seconds of icy black dislocation spanning a distance that might take a starship under Warp Drive several Terran years to accomplish, if such a direct journey was even possible.

The passage is not without its perils, however, as although no Warp-Drive or Gellar Field is required to use the Warp Gate, the passage through it is a turbulent one. It was quickly discovered that any less than sturdy vessels attempting the crossing were often badly damaged or even shaken apart by the stresses of the transit, limiting the Warp Gate's practical use to warships and other strongly-constructed voidcraft.

The gates appear utterly impervious to physical harm, protected by potent force fields the AdMech can't even begin to explain. The origins of the two gates are unknown. They were not built by the Eldar, and do not match the profile of the gates left behind by "the Old Ones".

The gates were once jealously guarded by the Imperium, but the Maw end is currently garrisoned by Tau ships, watch for signs of Tyranid incursions through the gate.

The Jericho end has no garrison - the gate there is shrouded by a thick field of space dust. This dust is made of exotic matter that defies all known shielding, and can disable even capital warship in weeks or months at best.
