Палетт

"Well, what do you expect?" he demanded. "I'm a Slytherin, I dress in black, and I hate all the so-called good guys. Narratively speaking, I'm evil. But I'm doing my best."

After finishing his incantation, and watching as the magic travelled across the dark night sky, Voldemort turned to the Dementor King, and greeted it mentally.

"Good evening, King Avtandil"

"The what?"
"The Hypocritic Oath," he repeated. "Every Healer has to take it. You swear that you'll do everything in your power to preserve life, unless that life is muggle."

He lifts a hand and begins to list off several different rough ideas he's come up with. "One of us writes in Riddle's diary. He will eventually possess the one who does and make his own way in there. At that point, the rest of us can follow. However, then comes the tricky problem of destroying the diary and making sure the one who is possessed is released from Riddle's hold at the same time. Otherwise, someone could end up dead, which I'm sure you all can agree is a far from ideal. Another idea is we all try to become animagus. If we are lucky, one of us will turn out to be a snake and the snake among us can hiss the password, letting us all in. A third possibility is we scour the castle for another entrance. I suspect there must be one. It would be quite foolhardy to not have another way in — or to escape — should something happen to the initial entrance. Salazar Slytherin wasn't foolhardy."

"Or we could find a way to change the password to the chamber, " Cresswell suggests. "Better yet! The language one has to speak to get it to open."
