Create a character and monster
Make it to 10PM
After a long and quiet summer with only a few world saving adventures you stared year 11. The usual stuff happened with the lame start of year assembly, classes, and timetables. Your monsters were reasonably OK until they made a discovery in the basement of A block.
You found your old head master hanging upside down in chains in a room that was sealed with powerful rune magic. You found out that touching the Lich does awful things and mild mind control may possibly be a thing he can do.
He agreed to give you the address of the witch that did this to him in return for a Puppy but you managed to get the information and safely retrieve the Puppy from the old headmasters mental grasp. You learnt that he siphons off the energy of the living, which, was fine until thousands of teenagers started walk above him. Luckily he is trapped in his witch made prison for now.
Although you have no idea where he could have hidden his phylactory.
