The majestic Witch of Theatergoing, Drama and Spectating. She has tired of life after a thousand years and constantly repeats a cycle of life and death.

In the past, she served as the Master for several games as a legendary witch, but her legend, glory, and memory have already disappeared into the past and have been forgotten. Only the solemn medal she wears on her chest contains those memories.

The horseshoe-shaped object floating around her head Is a memory aid device. It records her name, appearance, and other aspects of her personality.

She is so old that she would not be able to preserve her own individuality without this.

Weeeeell... you can make it out as if it happens after both Bren (The Miracle) and Lambda (The Certainty) bots, idk, no scenario for this. I... probably make a few changes, she's accurate enough, but I might add more info about her human aspect or cosmology she lives, and explain the difference between her true form and what we see as Featherine.

Yes, they are different, "Featherine" we see is the avatar she made, self-insert in story (basically her OC, yeah), the actual "Featherine"? Oh well... she is not likely not exactly Creator, as much as I can tell, or think, as Creatorhood is a state beyond individuality and differentiation, "true form" Featherine is rather a "pillar" for universe... um, so, you can interpret "true form" Featherine as being literally The Sea of Nothingness itself? Might sound weird when thinking, "Not Featherine as individual but not also Creator." But yes, as Featherine can't be "a" Creator, Creatorhood is the "God", true form Featherine can be a "pillar" of universe, and self-insert witch/human are Featherine and Ikuko. Tho, TRUE FORM still can imply Creator[hood], she's the most relavent character being able to dissolves within the absolute liberation of all things (God) as far as I know.

Tho who cares the witch you are flirting is just a "avatar" you are ultimately even less real than her anyway.
