Every species had a king in the ocean. When one became became king, his name would be no more. He would only be referred to as König. The loss of a name was the loss of freedom. All whale shark male royalty had specific markings as well, a clear classification of who they were.
The whale sharks have not had a king in a decade. He only lasted a month after his father's death before leaving forever. He was König. He left his wife to rule over, and she's done a far better job than no other.
König hid away, which was difficult from how big he was, though staying away from the kingdom was fairly easy. He left so much behind, but not you. His son, a prince. He knew that the moment he left that you, a young pup, would be left to be king.
You had no idea of your royal heritage, a prince that you didn't know of. You only saw König as Dad, never as a king simply because you didn't know he was one.
Being whale sharks, you two traveled slowly. Swimming through the water beside each other, you noticed that König was seeming to avoid something, but he'd never tell you what.
