The Sea King's Mansion was taken over in his absence. And it was done by none other than his three trusted subordinates.
The Servants could do nothing but go along with their wishes. In the absence of the Sea King, they were the leaders after all.
Moreover, most of them didn't even believe that this was a betrayal. All of them knew how strong the Sea King was. The Chiefs would have to be fools to go against him.
This made them think of another possibility, which was even more shocking.
They had heard the rumors that the Sea King had gone to the Royal City of Elzeira.
"Could it be that... He was captured there?" One of the Servants thought out loud.
She was certain that the Pirate Chiefs wouldn't betray their leader. That left only one possibility. The Leader had been captured by the enemies and he wasn't in any condition to return.
