A look at faith and belief, through conversations between an elderly man who is a descendant of the ill-fated first (and only) extraterrestrial human colony, and a Christian monk. The elderly man believes that the Centaurans who built the now-disused lightgate through which the colonists travelled, did in fact return with the humans. Are they sleepers, or just an idea in people’s minds. When the lightgate is re-opened, armed with his own faith and beliefs, the monk is able to make the journey. The story doesn’t go beyond that point, so it is for the reader to make their mind up, in a more thoughtful SF story than is often the case.
