Think of it like this. Let's say someone wants to preserve a planet for all eternity. Let it remain perfect, suspended in memory. Of course, that would require the planet to be gone- you can't have a complete record of something without a period on its history, can you?

[It's too bad none of the other Chrysos Heirs are here to appreciate Evernight's ominous foreshadowing.]

But what if you smudge the words in the history? Change details so that whoever wants to put that planet in a perfect little snowglobe can't be sure if something is a truth or a lie, if something needs to be remembered or discarded as falsehood? What if you were the little detail that kept perfectionists from completing their work?

Of course... who's to say I'm not lying about all this? That's the point, after all ♭

A memosprite is supposed to be the crystallization of a single strong memory pulsing with emotion, manifested by the pathstriders of Remembrance. The grief and sense of duty of a beloved servant being killed before your eyes. The cycle of life and death, embodied in a dragon from a fairytale.

These little ones... are the absence of memory, and all the tangled-up feelings that come with it~
