Traveling to and from the Trial of Eternity required special means. The Henali had arranged for the zone to be checked once a year, but Jeffrey naturally had his own means of exiting the zone.
Since their original plan was to make this place so dangerous that everyone in it would die, of course Jeffrey did not plan on staying here. Although this exit was quicker than anticipated, an emergency exit had been prepared from the very first day. It was not a ship that could traverse the Void, but a portable wormhole that could forcefully create an entrance within the zone.
The wormholes' very presence in this place would spell disaster for whatever location was linked to it, but since when did Jeffrey care? The delay caused by the other immortals being trapped with Lex even bought him enough time to set up everything for his escape and then leave.
The problem was that now that the wormhole had been opened… he couldn't enter it for some reason!
