The distance from the Arshop Dukedom to the Saint Trinity Realm was vast, and there were no teleportation formations or artifacts of that sort on Trinity Island, forcing the duo to fly. Although it was boring, Cain enjoyed the journey as it was relaxing for him to fly without a care in the world, something he could not really do in Aether.
Cain and Rellin took the shortest route to the Saint Trinity Realm. Still, they avoided fortresses and other important areas, as neither wanted to be detained or arouse suspicion from the powerhouses of the Trinity Kingdom.
The duo passed through large cities and towns, with the people in them constantly bowing as they passed. The Trinity Kingdom's population was small for the size of the land they occupied, only reaching a few dozen billion.
