Hmm I might go with a Somatic, I like shapeshifters. Thinking someone who can take on feline traits, and with training might even learn to fully turn into a wildcat. Kitty characters are a go-to thing for me.

They'd be curious and adventurous, and of course they'd have a pet cait.

As for Discord, in my experience RPs with them last longer than RPs without, but yeah toxic people are a concern. I RP with a few people here though, namely Crimson Flame, TheNoCoKid and Emeth, and can attest that they're respectful.
