A person? Larkin had also recognized a human's life signature from the man that was washed up ashore. He then walked at his normal pace as Artie ran up to the best that she could. If she ran normally, her feet would only sink in the sand. She had arrived at the side of the man, and she looked down at him without touching him. Her visual check showed that the man didn't seem to be mortally wounded, only fainted.
The locals had also come to help. It had been a long time since they last had someone washed up from the other ends of the lake. Since the lake didn't have a great current, almost everyone who was washed up didn't make it to land. This man seemed to be very lucky.
However, Larkin was more interested in the horizon. He didn't feel good about the appearance of this man.
