The journey to Vale wasn't long, as they were both located in the Falcon Sector, and each sector was like a fortified small region. Every sector had quite a number of cities, but the distance between each one of them was quite big.
Vale was only a few hundred kilometres away from Starlink Academy.
The number of Abyssal Creatures inside the sectors was far less than in the outside world, which was also the sole reason sectors were made.
Many people spent their whole lives living in just one sector since travelling between different sectors was very tough. After all, the sectors were cleared occasionally by the Army, but it was different for the outside world.
There were less than a billion people left in the world, so each sector held a very small population compared to their size. This was also the reason they were later made smaller to provide better security.
