Hogwarts: Voldemort's Ghostly Predecessor

“I don’t understand why everyone keeps discussing how a ghost could become headmaster, as if my taking the position is bound to spell disaster for you.” Metis sat on Gengar, floating in the middle of the Hogwarts Great Hall. “Over fifty years ago, I was already one of Voldemort’s most trusted elders. Wherever I go now, the Death Eaters welcome me with open arms. You could say I have every advantage on my side.” “Here’s my proposal: how about we let Voldemort into Hogwarts and hold a Holy Grail War? The winner gets any wish they want.” 【Host has successfully given someone a fright. Reward: Fear Points】 “So you’re going to surrender to Voldemort? I knew it all along, Metis! You’re an innately evil little ghost!” With Harry supporting him, old Moody berated Metis. Metis said nothing, silently opening the System’s lottery. 【Received Tzeentch’s Gaze (Ninth Time)】 Oh dear, looks like things got out of hand. Metis took the Time Stone from his robes, ready to redraw. “No, no! I just wanted to scare people and have a little fun (earn Fear Points).” (A story about a fun-loving ghost figuring out how to come back to life)
