"Is it far?" Asked Lucy as she gazed at the pink-colored sea, which seemed harmless, contrary to the rumors they heard about it on the way here.
"It's definitely in this sea but I can't pinpoint the exact location."
Makaze was constantly calling for him and the closer he got, the more intense the callings became. They were standing at the edge of a steep cliff and looking at the calm sea.
This place was a boundary between two universes so there were no mortals here and as it's dangerous, not many merchants are willing to pass through it. Furthermore, you can fly above this sea so ships are rendered useless in this environment.
The two didn't linger there for too long, they took flight, heading forward, where the blade's signal was coming from.
Actually, both Arthur and Lucy knew very little about this place but they had enough confidence to defend themselves if dangerous arises along the way.
