Okay hi! Now that I'm feeling better it is intro time.
Hestia and Aderyn shared a dorm in school. Aderyn wasn't exactly a creepy twin, but they did have the twin thing in common. She's a partial owner of Borgin & Burke's and works as a librarian for her day job. She could definitely use friends, so friends? Pls. My kingdom for friends for Aderyn.
Along with that, she'd probably get on pretty well with most of my Slytherins. Maybe not Pansy, who plays up the posh, refined pureblood thing instead of being creepy. Hector and Alastair would both appreciate her dark humor for sure.
I'm sure I'll find others to reply to her. Like Colin. Who might just talk at her for no reason.
