Ice, Ice, Baby!

Rita "Before we end the ceremony Mr Ollivander, shouldn't you know what wood and core was used in the construct of Miss Rivia's foci? That is your job isn't it?" she asks accusingly.

Ollivander shrugs with his misty eyes focusing on her, "Indeed it is Miss Skeeter, I however doubt you would find anyone in this world that would know what materials the staff was made from."

Rita "That is a rather broad and blatant statement you've just made there Mr Ollivander."

Ollivander "And one I'll stick by." he says, ending the conversation there.

Dumbledore "That will be the end of the wand weighing ceremony! Thank you all for coming, champions you should go back to your lessons, though this isn't required of you."

Rita "Dumbledore! Photo's!" she exclaims causing the old man to sigh.

Dumbledore "Very well..."

Skeeter pulls Fleur and Ciri together while depositing Harry in the middle of them. "Very nice, comfortable there Harry?" she asks, grinning as he tries not to touch anything inappropriate.

Harry "Very. Could you take the photo now?" he asks, the rest of the champions agreeing with him.

*FLASH!* *RUMBLE*

The camera goes off but is quickly followed by the school itself vibrating as if an explosion had gone off nearby.

Rita gives the camera man a look and he throws his arms in the air, "I didn't do nothing!"

Dumbledore "Whatever it was we must check it immediately, it seems to have gone off inside the wards which worries me." he says before quickly leaving in pursuit to find out what'd just happened.

Ciri rubs her arm anxious as she could almost predict who was responsible for it.

Now with Reima (Who's completely unrelated...)

Reima was sitting on the floor of the room of requirements pouring through the book on apparition. The theory was quite simple really, wizards use their magic to tear open a tiny worm hole that extends to wherever they wish to go, though this is just the best explanation he'd found in the books presented to him from the room of requirements. Most wizards didn't even know the theory however, instead just following these three steps :

Destination, choosing where you'll land and making sure it isn't likely to be inside of anything else.

Determination, just another name for will power. Most magic relies on the will to cast it and the lack of this will result in a botched job, this includes being splinched in two.

Deliberation, last but not least, as if you do not focus on what you want to happen enough you'll likely just get a random result. This may lead to you losing body parts, ending up somewhere you hadn't intended to go or just vanishing completely...

Yes, that's apparently all that's required for magical teleportation! Something that'd make all magic users in the Witcher universe green with envy. Reima theorises it's because Wizards have magical cores and Witches do not, instead they draw magic directly from their life force and those around them, sometimes resulting in gory ends for those that overuse it.

Either way Reima wished to be able to use this technique, not because he need them but because this kind of spatial tearing could be useful when applied to other spells, or infused with Elder Blood for instance? Indeed he's looking to try and apply spatial tearing in many different ways and hopefully will achieve some appreciable results, this'll be doubly so if he manages to create a new school of "Spatial" magic from it as he and Ciri would likely be incredibly adept at it.

Reima had just been meditating over what he wanted to do, he had successfully created a small wormhole that'd allow apparition but didn't try to teleport as the Hogwarts wards would probably tear him a new one, instead he's going to see what'd happen if you combined it with Elder Blood mana... Yes this is incredibly dangerous but he's alone and he reckons he could survive a couple mistakes...

His fingers glow turquoise as he channels the Elder Blood mana into them, once fully saturated he plunges both hands forwards as if he's about to open a tightly shut bag. His fingers disappear mid air but he doesn't lose their sensation... Until he does, he panics and pulls them back seeing them still attached to his hands but doesn't get much time to celebrate the survival of his fingers due to him being blasted point blank in the face by a huge torrent of icy mist, which shoots from the spatial distortion in-front of him which glows the same colour as his eyes.

Reima is instantly frozen solid by this and so is the rest of the room, the temperature instantly drops to sub zero, causing everything the mist touches to instantly freeze solid. Reima voluntarily lets his true form out which subsequently bursts into a violent pillar of dark red flames which temporarily hold back the icy beam of death still shooting from the spatial tear. The wind is just as bad as he's trying his best not to be blown around the room like a piece of paper stuck in a blizzard. He casts the most powerful Quen shield he can while slowly making his way towards the spatial tear, the amount of effort he's putting into trying to stop this exceeding the difficulty of fighting off the army of Izalith. Eventually he reaches the tear and throws his arm at it while channelling his Elder Blood through his hands, they swipe through the tear, destabilising it and causing it to implode, causing a huge explosion which rockets Reima into the wall. Creating a huge crater as a result.

Out of the crater a voice echoes out, "Man that fucking hurt!"
