It goes without saying that Jeskli was surprised to hear Kentucky's words. After all, no one had ever been able to stay in the center. Once they got inside, they wouldn't be able to tell which direction they were going anymore and would end up outside somewhere else, never being able to reach the real central area.
In a certain way, this was also confirmation that the Floating Islands of Time were affected by a fragment since it was a similar event to the Swamp of no Return. The only difference was that you could never escape from the swamp, but you definitely can in the Floating Islands of Time.
Jeskli didn't want to call much attention, so that's why he only stayed with Kentucky's group for a moment. Now, however, he had to go since he wanted to see what was happening in the central area. Of course, assuming Rean was right about being able to enter without ending outside.
Huhuhu!
