Ytrecht, a settlement on the world of Aricho, was positioned on a part of the planet plagued by intense weather events. These powerful storms made air travel a challenge, which meant that the town could only be reached during a few months of each year. Once the Nihil pirates landed on Aricho, the local defense was too weak to oppose them. As a result, the people were temporarily moved away, which tricked the Nihil into thinking the town had been deserted.
