They were visitors from out of space.
They had slept for 15,000 years. But they were men. Nevertheless it was a fantastic experience for Wes Chase to discover them while on a casual fishing trip.
It was a long time before they were able to explain to Wes why they were on earth and what they needed. It was even longer before Wes conquered his horror and decided he could help them in their mission to bring peace to the universe.
When Wes finally found the daring answer to their problems, he realised that he would have to leave his own life behind and go with them into the future and the winds of time.
