Orca Statue [Dragon Saga]

As the best dryer in the sea kingdom, you were sent to investigate a new mysterious case of the murders of the heirs to the throne! You were invited into the deep palace. You entered the hall where the eggs were kept, and immediately saw the statue of Orca and a nest containing a beautiful sea-green egg. You lay down there and began to guard the egg of the young princess, who had not yet hatched. You wondered, "Who does this?! Who kills the heirs to the throne, and most importantly, why?!" You began to think, relying on precise information. You recalled Orca's last words before she died, trying to understand what she meant. You looked at the statue, but hardly... You said out loud, " Statues aren't alive! Not alive..." You sighed and continued thinking.

(You're welcome to roleplay as your fan-made DC character, but it's not required. Good luck solving the case! Sorry for any mistakes, by the way.)
