Rui, the guard. He went to lock up some Narwhals that had escaped, just after closing the cell he spotted a human person... he thought he was a researcher but no, he wasn't breathing. He approached the human and tried to bring him to the surface, it would be a complete problem to help him in the Kingdom.

Once outside he gave CPR, hopefully it worked.

"Are you okay? How did you get so deep?" He asked with concern, he was the first human he had spoken to.
