Maleficent made a sigh as she heard Loki admit that he knew the mermaids' song, but only the humming of it. The song did have words, but since the mermaids don't speak in a common tongue of English, they don't tend to sing the song in words. The tune, 'My Jolly Sailor Bold', originated from a story that Maleficent used to tell Loki about the mermaid legend: A long time ago, a group of male Asgardian travelers sailed in a longboat, along with a lantern, to the shores of Tortuga. During the sail, they began to sing the song in words. Unknown to them, the song was so captivating, it seemed to have drawn the female creatures up from the deep. The mermaids entranced by coming close to them while they repeated the song, but in a hum, enchanting the men with their beauty. However, when one man got caught onto their enchantment by one female, all of them abandoned their gentle disguise, and attacked all the sailors viciously. It was then said that their attraction to man-made light, such as a lantern, and the song itself summoned them from the deep. Ever since then, the mermaids sang the song ever since, rarely in words.  

The mermaids of the Nine Realms were fierce, and some-what benevolent protectors of its water boundaries. This means that if any traveler comes upon them, they can sense if that person is good or not. Usually when the newcomer is alone, only a single mermaid would approach them. They would captivate their target with their beauty and lure their faces underwater with their hands, where the mermaid proceeds to look them over. If the person is proven good, the mermaids will stay benevolent and spare them. However, if otherwise, part of their skin would turn into pearly white scales with long fangs forming in their mouths while their eyes glowed their natural color intensely before proceeding to pull them fully into the water, dragging them deep into the depths where they drown and dispose of them. 

Maleficent kept her hand on Loki's cheek gently as he somewhat looked at her with undivided attention. "Remember this", she said before she began to sing in a melodic tune. It was slow, but harmonic. 

[i]"My heart is pierced by Cupid, I disdain all glittering gold. There is nothing can console me, but my jolly sailor bold. Come all, ye pretty fair 'maids, whoever you may be. Who love a jolly sailor bold, that ploughs the raging sea. My heart is pierced by Cupid, I disdain all glittering gold. There is nothing can console me, but my jolly sailor bold"[/i]
