Kraken

Leaving the Fish People tribe, Minos' group would sail east for the next few days, heading for the Kraken tribe, which lay at one of the outermost borders of the Marine Empire.

The Krakens tribe lay between the Marine Empire and the territory of the Sky Whales. 

The territory of the strongest creatures in the world was vast. It started about 300 kilometers from the south coast of the Central Continent and went all the way to the south pole of the Spiritual World, stretching more than 50,000 kilometers between the Marine Empire and another sea creature territory near the Continent of Beasts.

There weren't many powerful beast tribes within the Sky Whales, only on the borders of this vast territory. 

On one of these borders, there was one of the 20 strongest tribes of sea creatures, the small but mighty tribe of Krakens.
