In days of old, every room in a wooden sailing ship had an easy to access cabinet full of bottle corks. If one single, beautiful, hypnotic note could be heard carrying across the waves, an entire crew would scramble to plug their ears, lest they become a Mermaid's dinner. Many ships also employed a deaf crewmate as a further safety measure. With the upper body of an often very attractive lady and a lower body resembling a fish tail, Mermaids are effective at swimming through oceans and enchanting those of a nautical leaning with hypnotic singing. Those weak of mind would be lured towards the Mermaid's den, and the only mercy offered would be that they would remain in a state of bliss as a school of Mermaids ate them alive. Despite this behaviour, it is best not to consider a Mermaid 'evil'. Much like an anglerfish lures its pray with a light in the darkness, a Mermaid deploys song to find her supper.
