Sea Scoundrels are supernatural marine creatures who wreak havoc on ships at sea. Their magical powers can confuse compasses and oceanic field navigators. They can also cause food to rot, and bring nightmares to people. They have the power to phase straight through walls. They have an extreme weakness to tin, so they are usually destroyed with tin tipped harpoons or daggers. Once pierced by tin, they will soon die, and the curses they laid will be reversed. They will also die if brought onto land, as their life force is sustained by the oceanic fields. They also have a weakness to lemon juice... Lemon won't kill them, but it will burn them and suppress their powers briefly.
