hi there trisarahtops! i'm actually the owner of lovelorn, so uh. i can defs give a bit more context than jungler did!

lovelorn is a semi-private fantasy animated panfandom with a soulmate concept and optional regional story arcs to expand out our locations and engage in some mild site developments. the soulmate concept is pretty flexible, allowing for poly relationships, non-romantic soulmates, rejecting the system entirely, or just feasibly ignoring it if you'd prefer. and as a semi-private site (mostly because we're run by two staffers who both have full-time jobs and not enough time / energy to deal with extensive advertising or regularly dealing with problem members), we're able to take the best of both worlds in terms of things like a super relaxed application process and allowing in some more niche concepts you might not see elsewhere (like if someone wanted to do a human version of dvalin, sure, we'd allow it if it was done well).

lumine is indeed currently available, and she'd actually be pretty decently in-demand, both in a generalized thing (since we have a good many genshins currently in play) and specifically (since we have an abyss prince aether around + as our dainsleif player, i know i am particularly enthusiastic about the idea of "are you sleeping with my brother, dainsleif" threads).

we're not a personified / spirits site (sadly, i don't think there's one in animanga at the moment, which as someone who enjoyed the genre when i was in it, is honestly kind of a shame since it'd definitely be a cool thing to explore, but i digress), but of the two locations currently available, one is a slightly futuristic city and the other a more fantasy-esque setting, so you'd definitely be able to pull off her living in the modern area (or joining up with the knights of favonius knights of vitrei as an adventurer).

the big thing we might be a swing and a miss on is that, well, we're a smaller site with more laidback activity, so whether or not you're getting speedy replies largely depends on who exactly you're threading with (that was why i actually hesitated to shove us in at you, because i wasn't sure if that was going to be a dealbreaker for you). we do have an area on profiles for people to put down the typical speed they try to turn posts around in, so you're not going in entirely blind, but y'know, it is a thing i'll be honest about rather than pretend it doesn't exist (since i know from my own site-searching that i always appreciated when a site was more honest about where they fell short in regards to that).

even if you decide we're ultimately not what you're looking for, i definitely wish you luck in finding a place for her - as someone who's been struggling myself off and on with finding a good panfandom home, i know it's a pain-and-a-half to find more popular canons open, and i hope you can find a place that fits well for you!
