Jump to: navigation, search


Children of Monsters, sailors will often not return, but occasionally a child will wash ashore, the only legacy of a lost voyage Humans are constantly evolving and known to be intuitive and adventurous, constantly seeking out danger, though it is highly uncommon. This nature has led some humans to procreate with Sirens, though few have lived to tell the tale. Half-Sirens usually inherit traits from both parents, though their siren traits are more predominant.

Physical Description[edit]

To humans, half-sirens appear as eldritch sea-dwelling creatures, and to sirens, they're nothing but a familiar-looking human. In height, they are unnaturally tall and lithe, tending to be on average 4-7 feet tall, and from 100-180 pounds with men only slightly heavier than women. It is rare that Half-Siren men grow facial hair, but those that do only do so to hide their siren heritage. Half-Siren coloration and features lie somewhere between their human and Siren parents and thus show a variety even more pronounced than that found among either race. Sirens have eye colors that range from bright blue to a deep red, most Half-Sirens have eyes from their Siren parent, their ears are slightly pointed with a gill-like appearance.


Children of the Sea and Sky, of lost sailors and unseen monsters, Half-sirens lack a history of their own, though some adventuring ship captains, dread pirates, and even great musicians of history have had siren blood in their veins.


As scattered as they are, Half-Sirens take on the traits and cultures of the places they are born, though they often find themselves filled with wanderlust, or unsatisfied with their lives, even if they find themselves in a stable life they are still drawn to the deep blue sea.

Half-Siren Names[edit]

Half-Sirens are rarely born amongst humans and tend to have little to no parental care from their siren parent, though because sirens tend to speak a variety of languages and hear many things amongst the shore, the names are a diverse combination of multiples titles originating from Draconic to Orc. Sirens live in clans that are usually dubbed by sailors who notice their presence. Surnames though are a combination of Aquan and Primordial. Nicknames tend to also be Aquan and Primordial, First names, for half-sirens, are usually human. The following list includes common Siren and Human names, as well as combinations of both.

Male: Brinor, Malark, Zashar, Trinor, Frath, Lander
