The master would watch them through their hours of pain, he'd rub his chin with his brow raised as he watched their progress "...interesting.." he would say, somewhat surprised as all three make it past the painful hurdle. He'd grin as they finished "they all have the talent.... this is extremely rare... looks like I will need to prep the study room..."
After they've passed out he'd snap his fingers teleporting the children again, but this time to individual rooms. He'd look towards the golem "I'll leave their care to you, inform me when they awaken" he states before vanishing with his chair. The golem would seem to be happy even though his expression is fixed, he heads off upstairs to take care of the children.
It would be a full week later before the children start to regain consciousness, their minds slightly groggy, yet there is no pain. Their bodies would quickly feel full of energy and vitality. They would find themselves in very royalish rooms, they be in giant beds 18 feet wide by 20 feet long, making them feel tiny in the beds. There would be a canopy draped from the top of the bed covering the sides like royality would have. after leaving the bed the rooms would be fairly huge about 35 feet by 40 feet. There would be just about everything one could need, a work table, a study table, a dresser, book shelves, even though their empty, and much more. (I'll let the specific design be to your character's likings, plus required things, even color and such would fit to their liking)
This is when they'd probably notice their clothes of different, they would be wearing simply yet almost royal in design clothing. made with pure cotton, the boys would be wearing a White Tunic, like a T-shirt, it would have golden etching across the openings to the sleeves, neck, and bottom. Also what seems to be a pair of black cotton trousers that also have the same golden etching. While lydia would find herself in a white dress, it would also have golden etching at it's various openings, along with a few plant designs at the bottom.
Off to the side of their beds on a bedside table there would be a tray of fresh food, it would look like Elder tree ent soup which is fairly rare and known to be a great herbal food, with a side of bread and Pig Demon pork. Once noticing the food they would start feeling extremely hungry. There would also be a note next to the trays stating "once you've awaken and eaten, head out of your rooms and head Right (left for Lydia) down the hall and down two flights of stairs, head down the next hallway and enter the room on right side at the end. Also P.S. if you feel as if your current attire is unsuitable or dirty there is multiple other designs made from same material in the wardrobe, you'll be given back your old clothes later. -Alfred The Golem".
It would be directions towards the class rooms to begin their lessons.
Leon when he wakes up would glance around at the canopy, slowly getting up. He'd stare at the bed which had a verity of colors mixed into it, he'd rub his own neck worried if he made right decision but what done was done and he was glad to be alive. Getting out of the canopy bed he'd be shocked at how fancy the room was, he wasn't use to this kind of lavish place. Instead of focusing on the room he'd smell the food fairly quickly and without a second thought start devouring it rapidly. He'd only regain his senses when he finished and let out a big belch. He'd sigh and look at the note before nodding and leaving his room.
He'd find himself in a long hall way, that was a mix of magical and lavish. What was lighting the room was strange orb like objects in the ceiling, double checking he'd find it was the same for his room. He'd look at the other doors to find a room marked as 'Max' to the right of his room and room with 'Lydia' marked on it across from theirs.
