Sirens are capricious creatures whose singing can enchant other races (literally).
Sirens are not necessarily cruel, but they do enjoy enchanting and controlling others. They have a tendency to look down on other races, with the exception of elves, who they have a grudging respect for.
Sirens stand around 5 ft. in height, and weigh somewhere around 100-150 lb. Males are shorter and smaller than females. Sirens skin is usually darker, and their hair can range from blond to coal-black. Their eyes may be blue or gray. They are aquatic creatures, so they usually have an alternate form. Sirens live as long as Elves.
Sirens do get along well with many races, with the exception of elves, who have a resistance towards the siren’s music.
Sirens are usually neutral with a tendency towards good.

Dual Form. As an action, when on land, you can magically assume a bipedal humanoid shape similar to that of elf, human, or half-elf. Your humanoid form appears as your Siren form with legs in place of a tail, and hands in place of claws. In this form lose your swim speed, as well as your Natural Weapons. You do, however, gain a walking speed of 30, and follow all the normal rules for swimming. In addition, when you change shape from Siren to human form, you store your Siren essence in the form of a trinket, usually seashell necklace or seafoam silk shawl or item of that nature, and must keep it safe and secure. As long as you have this item in your possession, you may use your shapechanging ability at will and may maintain either form indefinitely. Without this item you may not use your shapechanging abilities to assume your Siren form until it is retrieved. If you are the target of a remove curse, greater restoration, heal, regenerate, or wish spell you immediately assume your Siren form and cannot use this shapechange until the next sunset (at which point you receive your new trinket.)
