YAAY THANKS FOR ASKING

I have two main ones - echo and darcy!

Echo - from Echo and Narcissus. I'd describe her as a justifiably hateful witch because Murr allowed her home forest to be cleared out to make a processing plant for mana stones so now she wants to kill him! Which like, understandable, but also she's not very smart and only good at building weapons so her evil plans don't really succeed.
She hates Murr, and Shylock knows about her but kind of pities her. She's also the main NPC in my made-up event, Requiem of the Wayward Scholar (West+South)
Her favorite holiday ... probably some kind of nature festival from old western country that no longer exists. But if you mean our world holidays, she probably would like Halloween - a chance to be scary!

Darcy - from Pride and Prejudice. I'd describe him as a wizard actively trying to love life (because he made a promise to his dead wife, Elizabeth, that he wouldn't spend the rest of his life grieving her so he tries actively to fill his life with things to do so he keeps that promise). He was also one of the financial sponsors of the revolution, who realized once wizards started getting executed that by alec's side was a bad place for a wizard to be so he fled west. He currently runs a museum in the city of affluence because he wants to keep history alive, he feels like it's his duty to do so.
He's friends with Rustica and they have tea together, and he knows Faust, though they both try to pretend they've never met. Rustica introduces him to the sage's wizards in my made-up event Minuet of the Lost Coin (West+East).
His favorite holiday would have to be maybe Easter? I think he would love Spring festivals and seeing the animals come out and have a good time.
