Lily is one of the clones of Fretia.
Lore
Lily is one of the clones of Fretia, the White Priestess of the Fount, created through science and magic, to take on her burden. She is one of the clones made to be dispatched to various sections of the Kingdom of End to contain the Blight. Siegrid is designated as her guardian, along with a nameless White Priestess who is deep asleep underneath a ruinous church. At some point, Lily died, leaving only a Priestess' Wish.
Physical Appearance
Lily, as a clone, looked identical to Fretia's other clones, with a pale complexion, white hair, and blue eyes. She donned a white dress with a black belt. She also had an amulet around her neck.
Personality
Based on her note, Lily was likely an easy child, as far as children go, she was likely not melodramatic and did not give her guardians a hard time. She was obedient, polite, and was quite the chatterbox. She seemed to be constantly looking for ways to have fun, as she often became bored, regardless of the horrors outside her sanctuary. Much like Fretia herself, Lily was selfless, willing to take on the Blight afflicting the residents of the kingdom so that they can be at peace even though doing so slowly corrupts their bodies and causes considerable pain.
Relationships
Fretia
Lily loved her "mother", Fretia, just as the latter did her.
Siegrid
Siegrid was specifically trained to protect Lily. During their companionship, Siegrid would teach Lily valuable lessons, the most enduring being that "good things come to those who do good".[1]
Lily
Lily loved having a new sister, even if they had never interacted. She was eager for her to awaken.[1]
