Water and Wolfsbane (гет)

Sorting through her stuff, Lily finds a box of old treasures under her bed, shoved away and forgotten. It takes her on a trip down memory lane, back to when she was a child playing games of make believe and magic with Severus. Because Hogwarts couldn’t have been anything more than the fantasy of two precocious little children, could it? After all, everyone knows magic isn’t real… Right…?
(Some inspiration is drawn from Fire and Hemlock by Diana Wynne Jones)
