@Heartstruck Hey! Welcome to Origin! If you'd like, I've got a few characters to offer - you can pick and choose which of them you'd like to meet!
Lamia frequents Fornax, since it's one of the few caves she can visit. She's friendly enough and might try to hug Heartstruck or play with her in the water, but she has difficulty communicating with words and is about as dumb as a rock.
Regalia kind of just drifts around and would definitely help give Heartstruck her name and accept her as its child, as it has a massive god-complex. As long as Heartstruck isn't directly disrespectful, it'll happily accept her and help her out however it can.
Deli is a bit of an oddball but a fun one. They's pretty friendly, although might try to tease Heartstruck or play a little prank on them. They're strange, but they just like to have fun and do art.
Oleander is friendly as hell but, if you're comfortable, she might fall into a mad obsession with her. This could possibly lead to future threads between them since she'll then do pretty much anything for her to make her happy...but also try to keep everyone else that poses a threat to their relationship far away.
