The Magesire family are mages that study and perform various types of magick or magic with the oldest known member being the Primordial Goddess Thalassa and the newest member being Lily Magesire.
The Magesire family are the most respected magical clans out there.
However, in modern times, the governments of the world secretly banded together to hide the existence of all supernatural, magical, celestial, and extraterrestrial entities while leaving a trail which came to be known as the various religions and cults and if all of the sacred texts were brought together, Humanity would figure out the secrets that the governments were hiding.
Each of the females of the Magesire Clan are given a copy of the goddess Thalassa's supposed dress that she wore which gives them more power.
