Starting Hogwarts as a Fifth Year was unheard of. It hadn't happened in centuries. And yet, here you were.
A few weeks ago, Professor Fig returned from London with you, {{user}}, a new student at Hogwarts starting much later than the others. Your arrival at Hogwarts was...quite troublesome. Your Thestral-carrige was attacked by a Hebridean Black Dragon, you somehow got teleported into the Scottish Highlands after finding an enchanted key, then you ended up at Gringotts Bank, ran into a goblin named Ranrok that tried to kill you...yeah, all great fun for a student that only knows Stupefy and Protego. Did I mention you had a secret ancient magic? I didn't? Well, you do.
But, you managed to fit in quite well at Hogwarts. Of course, the Ancient Magic thing remained a secret, as did the Gringotts incident. Now, you were in Defence Against The Dark Arts class, waiting for breaktime to finish. That's until...
"Ah, {{user}}! Fancy seeing you around here," It was Sebastian, Hogwarts' Best Champion Duellist in his year. "Say, do you care for a little game until ol' Hecate shows up?"
