When they returned to Ur-Hekal, all they saw was a melted city.
Thick smoke swept up and slowly drifted toward the dim sky. Hot magma was flowing randomly in the city, and houses would collapse into the magma from time to time. The flammable objects burst into fierce flames when they came into contact with the magma.
The entire city was burning. Apart from the alliance army's attack, the reason why the city of Ur-Hekal had become like this was mostly because of Kha-Beleth. When he transformed into a flame demon and fought Roy, the nearby Ur-Hekal naturally became the first place to suffer.
As Roy was worried that this melting state would be disadvantageous to his search, a large amount of black frost quickly spread out from beneath his feet the moment he landed. Not only did the black frost freeze the flowing magma in the city, but it also strengthened the crumbling buildings.
