Hexis: The prize

The Hexis campaign was not only about control and activation of the necron device. As the key powers of the sector investigated the necron ruins, it became clear that once activated the powerful artefact would create a channel of calm in the empyrean, undoing the Cicatrix and forming a stable passage across the great rift. However, the direction and form of the channel would be directed by whoever activated the device, leading to three possible outcomes, assuming the device was activated in situ. 

The resulting channel would exit on the other side of the rift in three possible stable configurations. The first would link the Lysis system directly to the warp lane to Ultramar, bypassing the Tau empire altogether. The second would provide a direct link to the Hadron Expanse from the Tau empire, while the third would connect the new worlds of the Expanse to the chaos held Enceladus subsector. 

Clearly these three options each favoured one of the main powers fighting on Hexis, but the creation of the Foramen Ignotum world still not be sufficient to exploit the new strategic reality. As with the Foramen Interdictum control of both ends of the channel, at the points where ships would have to gather before making the jump, would be of primary importance once the new passage was created.
