According to the fragments of memory from his past life, there was a room on the seventh floor that appeared only to those in genuine need, transforming itself to provide whatever the seeker required. It sounded absurd, like a fairy tale. But then again, so did talking portraits and moving staircases, and those were demonstrably real.
With the castle nearly empty, he could search the seventh floor freely without arousing suspicion. He spent the entire day walking each corridor multiple times, pacing back and forth in front of blank walls, thinking about what he needed. A place to practice privately, a place to study without interruption, a place that no one else could find.
It was late afternoon when the door finally appeared.
It was there suddenly between one blink and the next. A plain wooden door in a stretch of wall he'd walked past dozens of times. Rowan approached it carefully, half-expecting it to vanish. But it remained solid.
He opened it.
The room beyond was exactly what he needed.
Vast. Well-lit. With bookshelves lining the walls containing texts he'd never seen before. Lost books, forbidden books, books that hadn't been in the library. There were training dummies scattered throughout the space, practice areas marked on the floor, even a small potions station set up in one corner.
The Room of Requirement.
It was real.
Rowan spent hours exploring the room that first day, marveling at how it adapted to his thoughts. When he needed a comfortable chair to read, one appeared. When he wanted to practice dueling, the training dummies activated. When he wondered about organizing his notes, a writing desk materialized with fresh parchment and ink.
He told no one about the room. Not even in his journal. He simply referred to it as his "practice space" in his notes. The Room of Requirement was too valuable a resource to risk sharing. At least not yet.
On his second day of the holiday, Rowan tackled the dungeons. Beyond the Potions classroom and Slytherin common room entrance, corridors descended deeper into the castle's foundation. Most rooms were storage. Old furniture, broken equipment, crates of supplies. But some were more interesting. He found what appeared to be an abandoned Potions laboratory, far older than Professor Sharp's classroom, with cauldrons that had been unused for decades. He found a room filled with old school records. Parchments dating back centuries, detailing students long dead, professors long forgotten.
In one particularly deep corridor, Rowan discovered a door that wouldn't open. No amount of Alohomora could budge it. When he examined it more closely, he saw runes carved into the frame. Wards, complex and archaic, far beyond his current ability to understand let alone break.
He made careful note of the door's location in his new journal, along with sketches of the visible runes. Something worth protecting with wards this powerful was worth investigating eventually, once he had the skill.
On his third day, Rowan tackled the towers. Hogwarts had multiple towers serving different purposes. The Astronomy Tower, Ravenclaw Tower, Gryffindor Tower, and several others that seemed to have no clear function.
He climbed one such tower on the castle's eastern side, ascending spiral staircases that seemed to go on forever. At the very top, he found a small circular room with windows overlooking the Forbidden Forest and the mountains beyond. The room was empty except for a single chair positioned to face the largest window.
Someone had used this room regularly once. There were scuff marks on the floor from the chair being moved, and the windowsill showed signs of long use. But it had been abandoned years ago, perhaps decades. The dust was thick. The air stale.
Rowan cleaned the window with a quick Scouring Charm and sat in the chair, looking out over the landscape. From this height, he could see the Black Lake stretching toward the horizon, the Forbidden Forest spreading dark and vast to the north, and in the far distance, what might have been the lights of Hogsmeade.
He'd mentioned to his friends before the holiday that he might explore it. Satisfy his curiosity about what magical creatures and plants lived within its depths.
Now, standing here with the dark expanse spread before him, he reconsidered.
The forest was vast. Truly vast. From this vantage point, he could see it stretching toward the mountains, mile after mile of ancient trees and shadow. Professor Weasley's warning at breakfast echoed in his mind. About students who'd ventured in unprepared and never returned. Even with the Room of Requirement providing practice space and resources, even with his growing magical abilities, he was still a first-year student. Eleven years old with four months of formal magical education.
What lived in there? Werewolves, Edmund had mentioned. Centaurs who didn't appreciate human intrusion. Trolls, possibly. Who knew what else lurked in those depths? Creatures that even seventh years would struggle against, certainly.
His curiosity wasn't worth his life.
Not yet, anyway.
For now, the castle itself offered more than enough to occupy his time. The Room of Requirement alone contained resources he'd barely begun to tap. There were still entire wings of Hogwarts he hadn't explored, secrets buried in the library, techniques to master in his current subjects.
He would tell his friends he'd decided against the Forest. That he'd realized the risk outweighed the benefit. They'd understand. And when he was older, more skilled, better prepared, he could return to the idea.
Rowan turned away from the window and made his way back to the seventh floor.
Over the following days, Rowan established a routine. Mornings in the Room of Requirement. Studying the lost books, practicing spells, conducting experiments he couldn't risk doing in the dormitory. Afternoons exploring other parts of the castle, cataloging secret passages and hidden rooms.
The room provided training dummies when he needed them, comfortable chairs when he wanted to read, even a small potions station when he wanted to experiment with brewing. It adapted to his needs perfectly, anticipating what he required before he consciously asked for it.
This was where he worked through Theoretical Foundations of Spell Modification that Lawrence had given him, cross-referencing it with the other texts he'd found in the Room. The combination of theoretical knowledge and practical experimentation accelerated his understanding dramatically.
Armed with this theoretical foundation, Rowan began experimenting more systematically with spell modifications. He documented each attempt in his journal:
Experiment 14: Modified Knockback Jinx - Added counterclockwise twist before final thrust. Result: Spell trajectory curved left approximately 15 degrees. Possible applications for hitting targets around corners?
Experiment 21: Modified Unlocking Charm - Extended final syllable by half-second. Result: Charm worked on complex lock that resisted standard casting. Hypothesis: Duration of incantation correlates with complexity of mechanism that can be unlocked.
Experiment 27: Modified Shield Charm - Visualized shield as dome rather than flat barrier. Result: Complete spherical protection, blocks attacks from all directions simultaneously. Significantly higher magical cost but superior defense.
Each modification was carefully tested, its effects recorded, its potential applications considered. Some experiments failed spectacularly. One modified Severing Charm cut through his desk, the floor beneath it, and part of the foundation before Rowan managed to cancel it. Others produced unexpected results that proved more useful than what he'd intended.
