Ponysona 4, the Campaign.

“The first mystery is of the Demon’s Locker. Locker 1313 over in the science building is large enough for a pony to fit in, however... There was this one stallion who was bullied and shoved in there. When the two jock ponies opened the door.... He went missing. Anything that went into that locker disappeared. Ponies, books, Papers, electronics... Every once in a while there’s some ponies who leave a note on the door, say ‘goodbye’, and shut themselves in there. Never. To return. Again.”

“The second is the Antigravity ramp over in the Engineering wing.. Supposedly, dropping anything at the bottom of it makes it roll up the ramp aaaall the way to the top. Some pegasus filly snuck into the school and laid at the bottom, and the next day she said she had rolled all the way up without moving once... and didn’t stop until she had left.”

Tilt perks up at this second one. “Oh, that’s pretty normal. When I was a little filly every now and again you’d have ponies fighting it out in the streets, jumping up and down off roofs. ”

“The third is the Death Cough of the Lost Student over in the boiler room under the Weathercrafting Department. Supposedly, if you go to the boiler room in the middle of the night, you can hear what sounds to be a loud groan followed by some coughs. If you listen closely, you might be able to make out a stallion’s hoarse voice calling out for help, but if you answer and find him.... You’re dead.”

“The Fourth mystery is the Walking Shadows. Thought you’d be interested in this one especially, Tilt. The Walking Shadows are when you walk through the school after hours, sometimes you may come across a light flashing your way, and you’ll see your shadow on the wall... Right before it dashes the other way. You might even hear your own voice, if you’re unlucky enough.”

“The fifth is the Crushing Course. There are a couple of night classes for astronomy at Ineighba high, but nopony or griffon or zebra chooses them. Why? Because that late at night, even the teachers are afraid to be in the astronomy classrooms at night. Every night, anything that’s left in there. Be it phones, electronics in any way shape or form. is found smashed to pieces the next morning. Some say, that the red coloring of the rooms there is because a colt once spent the night in the room, and the next day his body was what was found smashed.

“The Sixth is the Fiendish foal. Wandering around the home economics wing, though supposedly he was found all around the school, a young earth pony colt can be seen wandering the halls with a sinister giggle, asking ponies to play with him. If you accept, the pony spirits you away to the underworld, never to be seen again, leaving only a single drop of blood.”

“The final mystery is the Wraith. Supposedly If you go to the library recently, you can find piles of ash all scattered around the history section, even though the librarian there cleans it regularly after school. A pony was walking late through the library and saw a green, almost phantasmal pegasus stallion before she dashed off in fear. On her way out, she heard a loud ghastly wail that sent chills down her spine as she left faster. She went back in the morning, finding ashes where she had last seen the stallion, books on demonology and the bloodiest wars in history rewriting books throughout the stacks, and a few small green feathers that disappeared at the slightest touch."

1d20+8 = 8+8 = 16.
Points for bonus and roll synching up, but I don't think I get much.
