Gabriel was still focused on the strange pond before him, when he noticed that the sound of battle had stopped. The ground wasn't constantly shaking anymore. It was as if the battle outside had come to a halt.
He was curious about the outcome. He had seen how strong Ezekiel was. So he was sure Ezekiel wasn't going to be defeated. That made him feel that the battle was Ezekiel's victory.
Eventually, he decided to leave the Palace. He glanced at the strange pond one last time, before turning around.
It doesn't matter even if the pond was anything species. It had to be buried with the entire palace!
As Gabriel walked out of the palace, he destroyed every foundation of the Palace that helped it stand up.
Right as he stepped out, he destroyed the last foundation as well, watching the entire palace crumbling down, burying everything inside.
