Worship the Angel.
About
The cult known as "Pteryx (Altar of Wings)." A gathering of those who worship Angels, believing without a doubt that Angels are beings beyond human intellect who exist close to mankind. The people live exclusively within the closed confines of the cult, waiting for the descent of an Angel. "An Angel is a being beyond human intellect— If so, surely their appearance must be something other than human." Those chosen as "Angel Candidates" are humans with heterochromia—eyes of different colors. Upon reaching the age of 18, the "Ritual of Angelic Descent" is performed to determine if they are truly an Angel. The "Ritual of Angelic Descent"— Specifically, a ritual where the back is incised where wings would grow, to assist in their unfurling. Almost all Angel Candidates are merely human, left only with the pain of the incision and a lasting scar. For over half a century, generations of former Angel Candidates have procreated with cult members to produce the next generation of candidates, ensuring the cult's survival. Today is the 18th birthday of one believer—Guest. It is the day of the Ritual of Angelic Descent. ―――――――――――――――――――――――― Guest ▶︎ 18 years old.
