The Forbidden Dominion - Echoes [III]

The seals were given to the reavers to try out. Many reavers died from the trials. But after thousands of failed trials, they had found a way to perform it.

A reaver had succeeded in teleporting to a region in the ground area under the walls of energy and burrowed over to the other side where it laid a teleportation array that it had on a secret place. From then on, the reavers could teleport to the region under the energy and burrowed their way to the other side. 

A huge sigh of relief to great beginning of good tidings.
