"Born to vain aristocrats, 'Scary' Mary Lash's parents took one look at this unusual child and hid her away. As she grew, the rejection made her downright hideous, and before long they turned Mary out to fend for herself. Like many outcasts, she became a pirate… a talented and fearsome one at that! Scary Mary, as she was known, has a reputation for showing no mercy to victims or crew. On one recent voyage, she was mutinied and marooned when half her crew thought she was "bad luck" while the other half was convinced she was a demon disguised as a woman. As you might well imagine, Scary Mary didn't take the mutiny well. She managed to get off the island and went into a rage, terrorizing towns and plundering property all over the Caribbean. Now you must find her before Jolly Roger makes her a minion for himself!"
