Salt has been used for years to ward off evil. But as the oceans are drained and filtered to be drinkable, the evil that was trapped there is unleashed. All the Sirens, Sea Monsters, and ghosts are now free. The ocean still had a big secret. The secret is that as soon as the monsters became loose all the coral became poisonous. All creatures besides the monsters are immune to this specific poison.

But the plan backfired on the ocean. For that sunset was when everything rose from the ocean to kill.

They avoided the coral. Eventually one touched the coral but didn’t die.

Now the monsters of the sea are loose. FOREVER.
