At the Center

Once he heard it, Rean sent his sense into the Dimensional Realm. There, in the gap connecting the outside and inside worlds, the Seal was barking.

*Ort, ort, ort, ort, ort...*

It's astral body shined every time it did, seemingly interacting with something outside.

"Shit..." Rean quickly took his attention back to his group. "Everyone, check that weird seal in your Pocket Dimensional Realms."

They didn't know why Rean asked that, but they all sent their senses into their Pocket Dimensional Realms. Sure enough, at the gap between the outside and inside, they noticed the Waterdog Seal barking nonstop as it shined every time it did. "It is... barking? Barking at what?"

"As I thought..." Rean nodded. "Casper, change of direction. Follow my instructions and fly as fast as you can."
