The freighter "Mary" crashed at sea, and only 5 of the 32 crew members survived. Five people took a boat to a desert island on a new route to survive, but they accidentally stumbled into Raleye, where they encountered giant blood-sucking locusts, strange shadows in the dark, and an island that could run away. They missed two rescue opportunities, and eventually both people and the island disappeared.
Intent: Nature is great, and people must live in awe with a sense of awe. The shadows hidden under nature have their own indescribable horrors.
