Kelgarries wanted the job done in a month, but he was a soldier, not an engineer. The construction and precision placement of twin temporal gates, one at the highest point on Vila do Porto, one of the smaller islands of the Azores, and the other at the epicenter of the Tunguska Event, some 65 kilometers north-northwest of the town of Vanavara, could not be rushed, particularly at the stage of configuring the fusion generator for each and then applying power to the gates.
Both gates had to be absolutely synchronized in power output and frequency for their plan to work.
The plan? To intercept an experimental alien space and time craft that launched nearly 4,000 years ago from what used to be the main island in the Atlantis chain, where now remains only the tiny islands of the Azores, and due to explode in the atmosphere above a remote portion of Siberia on June 30, 1908. The field the gates would generate between the launch and crash points would create a nexus in the time stream intersecting with the ship and sending it off source to another place in the far distant past.
