There is a wizard who frees a dragon that was sealed within a book for centuries. Every detail of the dragon's body, height, colour, features have been recorded thoroughly by the wizard so that the dragon's restoration to flesh is successful. I'm wondering what kind of magic would you class this as? It wouldn't be necromancy as the dragon wasn't killed, it was imprisoned. Maybe conjuration but it isn't that more to do with spirits and ghosts, and also the dragon is brought back in its true, physical form. It's a toughie! What do you think?
