Wormhole

The key component in The Plan. Endivar Valdus uses its power to kickstart the events that would lead up to the conclusion of The Plan and misalign the relative boundaries of the Centri sectors.

According to Endivar, Liam is the reason that the wormhole exists in the first place, despite the obvious assumption that Valdus himself created it.

With the help of Blythe Torres at the end of Book 1, Liam disables and destroys the wormhole.

Even with the wormhole gone, the sectors are now unstable and prone to further attack from Valdus.
