The South Pole and the Arctic Ocean 

After three weeks of traveling by boat, Minos' party had left the Marine Empire's territory and entered the Sky Whales tribe's southern border.

After more than two weeks since leaving the Krakens' tribe, the group had finally entered the main part of the Spiritual World's South Pole, the most icy area in the entire world.

In this area, the water was so icy that countless icebergs floated on the sea's surface. At the same time, frozen mountain ranges at the bottom of the ocean which provided beautiful scenery for anyone traveling there.

Even though they were traveling along the ocean floor, Minos' group got the same impression as if they were traveling on foot near the Endless Snow Mountain Range, where the highest peaks in the world were located.

The only difference in this part of the world was that this was the ocean floor, and they were covered by water.
