"We don't have much contact with the marine clans of the other inner sea regions. However, eight marine clans are ruling the Inner Sea, one for each of the eight seas."
"Among the eight seas, we do know our neighbor, the Emperor Crab Clan, rules the Northwestern Sea, and our other neighbor, the Fighting Dolphin Clan, rules the Southwestern Sea."
"If you seek to visit them, this subordinate suggests you choose the Fighting Dolphin Clan first, my Lord. The Fighting Dolphins are much more reasonable than the Emperor Crabs."

The Emperor Crab Clan was a highly aggressive crustacean species due to its voracious appetite. Not only could they grow countless times larger than their earliest ancestors, but they also ate anything and everything, including their own kind.
The Emperor Crab Clan didn't have high battle power.
