So, were WOULD be a good place?
Unfortunately, as far as I can tell, the only Temptation's Ballad fanwiki is the one on Fandom
if you would take it upon yourself to make a new, better fanwiki for TB on any of these other sites, I'll gladly help "advertise" it, as I've been doing to the Fandom one
but atm, I don't dislike Fandom enough to go to the work of building an entire new wiki from scratch
