Whyyyy ;.; I just realized (remembered?) Lilyheart is a name in the Canon warrior's series and I already have a cat with that name already written down everywhere in the plot notes when it comes time for her to exist. Then I forgot about Harestar being a cat, too. But my Harestar is a different gender, so hopefully that helps some.
At this point, if you see a name in this upcoming AU fanfic that matched/matches one that exists/existed in the series, please don't get mad/upset. I'm just tired of creating out some really great and fitting names and learn they already exist. I'm just going to create names and stick with them. Then the fact I haven't read past the first half of The Broken Code arc's book 1 (can't remember the title name rn, sorry)
It's happened with both Harestar and Lilyheart and there were another two that I can't remember the names of right now. (Been awhile). And note: if a Willowheart appears in canon, I'm sorry. I'm definitely not changing it, whether Willowheart ends up a good cat or a controversial/bad cat. "Willowheart" has been my Warrior sona since 7th grade (literally over a decade ago) and I'm not leaving it behind lol
