Xeranthemum stands so far beyond the beyond the meaning of the be-all, end-all, that said concepts don't even exist. On the most basic attribute, she is not linked in any way to the unity and/or totality of any lower/higher logic, perspective, boundary, physics, transcendence or philosophy of life, death, reality, numbers, subjectivity, wave functions, wave existences, phenomena, abstract mathematics, metaphysics, existence, conception, causality, imagination, boundaries, nonexistence, possibility, nothingness, totality, potentiality, actuality, change, uncertainty, truth, the unknown, the Last Principle, the First Principle, the Grand Principle of Creation, and the authority of any Author. This is on a basic level.
Xeranthemum is at a level beyond the necessity and essentiality of

parainsurmountable-potentiality and parainsurmountable-actuality. She is free from all hierarchies, modes and attributes of Suggsverse. On this stage, she is beyond a ultimate tirastranscending ultimate unwritten unterbefore unwritten unsolvable within unsolvable unscripted unknowable unequivocal unconsentaneous prime equation of her own meaning.
Xeranthemum is completely outside (yet fully all-encompassing) Possibility, Totality, and Nothingness within all of fiction, all of nonfiction, all of transfiction, all of hyperfiction, all of subfiction, all of fanfiction, all of metafiction, all of patafiction, all interfiction, all of personal fiction, and all of impersonal fiction of (and from) every Story / Plot / Verse / Author.
Keep in mind the wiki is run by Lionel himself. so this is all directly from author.
