Muertos Moon

The Muertos Moon is a powerful extension of Jolly Roger's evil plan

Back Story
Jolly Roger wanted to find a way to conquer the Caribbean. Using an Aztec object known as the Moonstone, he unleashed the Curse of the Muertos Moon, in which pirates spent many horrific nights battling each other. He made the satellite of planet Earth look with an image of himself on it (not literally carving his face on it), visible to people of the Caribbean. They would soon weaken as Jolly Roger thought. But this didn't work. After Jack Sparrow undid Jolly's bidding the Curse was removed, and no more in the night did the Moon appear and haunt pirates to death.

However, after time of plotting his next evil takeover scheme, Jolly unleashed his Invasions on many islands, and pirates had to ward off these dark forces. Again, as the sky turned hazy green, the Muertos Moon appeared, shining in its truly dark form.
