Gate of Ivrel

Time rebounded, indulged in several settling ripples of distortion, and centered at some point before the overextended Now.

At least, so the theorists from the Science Bureau surmised, when the worlds that survived were discovered, along with their flotsam of qhal relics that had been cast back up out of time. And among the relics were the Gates.

The Gates exist. We can therefore assume that they exist in the future and in the past, but we cannot ascertain the extent of their existence until we use them. According to present qhal belief, which is without substantiation, world upon world has been disrupted; and upon such worlds elements are greatly muddled. Among these anomalies may be survivals taken from our own area, which might prove lethal to us if taken into backtime.

It is the Bureau’s opinion that the Gates, once passed, must be sealed from the far side of space and time, or we continually risk the possibility of another such time-implosion as ruined the qhal. It is theorized by the qhal themselves that this area of space has witnessed one prior time-implosion of undetermined magnitude, perhaps of a few years of span or of millennia, which was occasioned by the first Gate and receptor discovered by the qhal, to the ruin first of the unknown alien culture and subsequently of their own. There is therefore a constant risk so long as there will ever exist a single Gate, that our own existence could be similarly affected upon any instant. It is therefore the majority opinion of the Bureau that utilization of the Gates should be permitted, but only for the dispatch of a force to close them, or destroy them. A team has been prepared. Return for them will of course be impossible; and the length of the mission will be of indeterminate duration, so that, on the one hand, it may result in the immediate entrapment or destruction of the team, or, on the other, it may prove to be a task of such temporal scope that one or a dozen generations of the expeditionary force may not be sufficient to reach the ultimate Gate.
