Gravis swam along the ocean floor with quite some speed, thanks to his Spirit. Yet, no sand or water was being disturbed. That was also thanks to his Spirit since it moved the water around him and then back into place. This made him move without sound nor wave. He moved almost like a ghost.
Gravis traveled like this for several hours. He saw a lot of Spirit Beasts, but none were up to his standards. The main reason was that they were simply too big. Beasts who lived in the sea were generally bigger than beasts living on land, and, apparently, that was also true for Spirit Beasts.
On top of that, Gravis also saw some mid-rank Spirit Beasts and even a high-rank Spirit Beast. Sadly, all of them were just too big to eat. He would need months to eat them.
After some hours, Gravis arrived in a peculiar area. It didn't look any different from the other areas at first glance, but something was definitely different.
