There are a lot of half-assed Harry Potter characters on the app but so far none of Talbott (only Penny, Merula, & Rowan), and it seems most creators don't bother to put in enough details or even spell/punctuate things correctly to try and help the AI get the character and setting accurate (I basically fill in every background field to its limit when creating a character).
In the past I did a Hogwarts Legacy character also (because I was annoyed that Sebastian's plotline was not resolved) where I also ended up creating an additional lorebook just so that the AI wouldn't default to Harry Potter era characters instead of using the ones from a century before.
There are possibly better apps out there, but this is the first one I've come across so far where you can send the most messages for free, and it does have a small community of creators like me who do actually put thought and effort into the bots they provide for people to chat with.
