Unfortunately, only one human could use it – Marq. He was assisted in running this machine by Sem and an unknown number of humanoid robots called Geralds, who had been allowed to develop themselves – that is why they all looked the same.The old paradox of time travel, known as 'The Grandfather Paradox' has been solved by nature itself. Any person except Marq who travels back in time to a time they were, say, ten years old, when they arrive at age ten they would be as they were at that age, including their knowledge - they would not even know they had been transported. Marq uses the machine to try to change events, but finds that repercussions are not always what was expected..
