Convergence

Thanks to his manipulation of Sunlight Energy, none of the Sunlight Beasts could feel Rean's presence anymore. That allowed the twins to flash past the fastest routes without a care for the world. It goes without saying that no fights gave them a great advantage regarding speed. Even though they weren't in the Transition Realm, they arrived in the central area with a few minutes to spare compared to the others.

There, they saw a tower at the center going several kilometers high, and at the very top, a giant ball of fire burnt nonstop.

"So much Sunlight Energy..." Even Rean felt a little uncomfortable now. 

Roan ignored that, though. "That thing is probably the reason the Sun Urpins are making their way here. They can feel its presence."

Sister Orb added. [It is also that thing that acts like a sun in this palace and probably the Sunlight Realm outside. It is the reason for this place to have no nights.]
