For instance, Ron two years ago only hemmed his second-hand dress robes and never thought about using Transfiguration.
Of course, it might be that he simply didn't think of it.
"Don't worry," Kael waved his hand, "As long as Professor McGonagall and Dumbledore don't come, no one will be able to tell."
Then he transfigured a set of clothes for himself.
"That's good," Conna said happily without doubting Kael's words at all. She twirled around and noticed that besides being more convenient, these dress robes had another advantage.
Due to the Transfiguration, it was essentially the school uniform, with no change in the feel or weight of wearing it, which was much more comfortable than the heavy and tight dress robes.
Since it happened to coincide with Halloween and a ball, Slughorn invited a lot of people, and along with their respective dance partners, the number increased even more.
Kael and Conna had just entered Slughorn's office when they heard a cacophony of sounds, laughter, music, and loud talking growing louder with their footsteps.
Slughorn had enchanted his office to look much larger than a typical professor's.
The ceiling and walls were covered with drapes of various colors, and on top was a golden pumpkin lantern, but inside were numerous little elves with lanterns, flying around as if countless points of light were constantly twinkling.
The servers were house-elves from the kitchen, weaving through the crowd with trays full of various drinks.
"Oh... Kael, Conna, my children!" They hadn't even entered the door when Slughorn's booming voice called out, "It's truly difficult to invite you... But as I said before, you can't keep avoiding me forever."
"Professor, what you said is just too sad," Kael said. "We very much wanted to come to the party, but unfortunately, Professor Snape has been interfering, preventing Conna from coming.
"Moreover, you must know how boring work is at the Ministry of Magic."
"Oh, yes, I know," Slughorn blinked and said with a smile. "I was just joking; today you've finally gotten your wish, haven't you?
"Well then, come in quickly, there are so many people you need to meet." He happily led them into the office.
Kael and Conna exchanged a glance and reluctantly followed.
"That's Worple, my former student." Slughorn pointed at a short man talking to Harry over there. "He's the author of 'Blood Brothers: My Life Among Vampires'... and of course, his brother Sanguini."
The book title sounded a bit like Lockhart's style, but it was completely authentic. Worple truly lived among a group of vampires.
The handsome and tall man next to him with dark circles around his eyes and an always sleepy look was indeed a genuine vampire.
But only when girls passed by did he become more spirited, licking his lips with a hungry glint in his eyes.
Apparently sensing Kael's gaze, Sanguini turned his head to look.
He immediately noticed Conna, the light in his eyes brightening as he realized she had a unique scent unlike other girls.
It was like the rosemary garnishing a steak, making him salivate.
Sanguini suddenly found the pie in his hand bland and couldn't resist taking two steps forward.
"Vampires like talented wizards, especially witches," Kael explained to the frowning Conna.
"I know, Lockhart's book mentioned it," Conna said. "I just find it strange.
"Not to worry," Kael said, pulling out his suitcase and opening it slightly.
The students attending the ball didn't notice anything different, continuing their activities, while the vampire stood frozen.
For a moment, he instinctively sensed several extremely dangerous scents, each capable of easily tearing him apart.
Sanguini suddenly sobered up, turning rigidly as if nothing happened and trying to hide behind the shorter Worple.
"See, it was easily resolved," Kael said with a smile, skillfully grabbing the Niffler that leapt out from the suitcase and stuffing it back in.
