After a whole month of traveling, Gravis and Orthar arrived in an environment with around quadruple the Energy density. This Energy density was about equal to the Core-Continent of Gravis' previous lower world. Along the way, they had also seen two other high-rank Spirit Beasts.
The first one had been a sizable starfish with a diameter of around 300 meters. Orthar had immediately been interested and had engaged it in combat while Gravis watched.
Their tentacles clashed against each other in a constant wrestling of superiority. Yet, due to Orthar's intelligence, he managed to turn the starfish around so that it was facing him with its back. At that point, Orthar's beak did the rest.
"I haven't felt this alive in eons!" Orthar transmitted to Gravis in excitement. "I feel like my youth is coming back!"
Gravis only smiled and let him have his moment of joy. Orthar hadn't fought a powerful opponent in who knew how many years.
