The Kids Aren't Alright

Set at Hogwarts, ten years after DH. Four students start an elective archaeology class only to find that things weren't quite as stated on the tin. Hijinks more than likely ensue. Mostly OC-centric with a fair sprinkling of cameos. Mostly canon, though a little bit of ret-con/AU because the authors are huge Arthurian legend nerds. Co-authored by Andavri. TW: Attempted rape.
