Chapter 123: The Other World.

The portals began appearing across all the fleets after the horns were wailed. 

The fleets were structured in a particular way which allowed them to fly. At the bottom, there were large growing crystals which were what gave it it's levitational properties. 

The sails were what controlled the direction in which the ship moved, an ability user with wind magic or another ability would make this easier. 

Otherwise, one could do what most of the other ships did and use another growing crystal with wind properties. 

These crystals made their lives many times easier. 

One by one, the fleets began to push forward through the portals, entering it before it could close down. 

This included the King's fleet where Gray and the group were. 

As Gray's ship began to leave, he heard a voice calling out to him from the city. 

As he rushed over to the deck to see what it was, his eyes widened in surprise.
