wasting time on Pottermore at the moment and… wait a minute… NEW UPDATES?!
Oh, gods, are we getting background info on Peeves? :D
(What is it about Harry Potter that bring out my inner fangirl? I do not know.)
"Several concerted efforts to remove Peeves from the castle have resulted in failure. The last and most disastrous was made in 1876 by caretaker Rancorous Carpe, who devised an elaborate trap, baited with an assortment of weapons he believed would be irresistible to Peeves, and a vast enchanted bell jar, reinforced by various Containment Charms, which he intended to drop over the poltergeist once he was in place. Not only did Peeves break easily through the giant bell jar, showering an entire corridor with broken glass, he also escaped the trap armed with several cutlasses, crossbows, a blunderbuss and a miniature cannon. The castle was evacuated while Peeves amused himself by firing randomly out of the windows and threatening all and sundry with death."
I love you, Jo Rowling.
