Gravis and Skye flew for multiple days. Even though Skye flew very fast, even creating a sonic boom at the start of their flight, the Middle-Continent was just too big. The Core-Continent was a circle, while the Middle-Continent encompassed the Core-Continent in a bigger circle. The Outer-Continent did the same with the Middle-Continent.
Gravis and Skye were currently south of the Core-Continent, and they were flying to the south-east of the Middle-Continent. Every major guild had one of their headquarters in the north, east, south, and west of the Middle-Continent, while the Heaven Sect only had two. One was in the south-east of the Middle-Continent, while the other was in the north-west.
