"Well this is inconvenient." Harry groused as he walked through the corridor to a set of stairs that didn't move. Halfway down the corridor a large door caught Harry's attention, it looked a bit different than the other doors in the corridor. "Ten to one odds that this is the forbidden part of the corridor." Harry mused to himself. He still reached out and tried to open it just out of sheer curiosity, but found it locked. With a wave of his hand and a wandless Alohomora the door actually unlocked. "Why wouldn't they place a stronger locking charm on the door? First years could open this." He wondered, after all he was a first year and he'd just opened the door. With his curiosity peaked Harry cracked the door open slightly and looked into the gloomy room. There in the middle was a massive dog with three heads snoozing on top of a wooden trapdoor. Harry, eyes wide, gently closed the door back and used the basic Colloportus Charm he'd gotten to work wandlessly a few days into November to re-lock it. "Well, now I know why it's forbidden." But did he really? His curious mind questioned. After all the trapdoor was clearly part of the forbidden corridor and who knew what lay beyond it? Trying to shelve his curiosity Harry quickly made his way up the stairs and into Ravenclaw Tower.
A few of his Housemates inquired about when the Test Frame for the Common Room would be ready but Harry gave them a vague time of the coming weekend. He quickly got to his dorm room and locked the door behind him. It was time to see who had written to him. The letter from the Enchanted Object Company was basically an offer to be the exclusive sellers of his products. Well they could forget that. Owl Order gave him much more freedom than signing any contract with a large company would. The next letter was from an Enchanter in Wales who'd asked about the Runic Language Harry had used for his device. Harry didn't see any harm in telling him, his runic sequence was merely a derivative of Elder and Younger Futhark linked together. But he'd only tell the man he used Futhark Runes so as to better protect his own secrets.
"Huh, this ones from the Netherlands." Harry mused as he opened the next letter and found a missive from another Enchanter. This one was asking whether or not Harry was sure of his Scouters' accuracy in measuring Magic. Harry would write to the man explaining how he'd designed his basic unit of measurement. That should encourage more understanding and faith in his Scouter as an accurate tool for measuring mana.
The fourth letter was from a Magical Scholar in France. Thankfully this, Madam Aveline according to the letter, had written in English as Harry couldn't read French. The Scholar was curious about his thoughts on Magic and his desire to quantify it. This seemed like a good intellectual pursuit so Harry would make sure to write back to the woman. Maybe he should learn some French? It couldn't be anything but beneficial to his future business endeavors. He did get a chuckle when the post script had asked if he would sell her a Scouter directly for the same ten Galleon price as through Owl Order. He really needed to either get his Transfiguration skills up to the strength and finesse required to shape metal or find a place to build a forge in Hogwarts. Though acquiring more metal might be far more expensive than he'd like.
The fifth letter was from another Scholar, this one in Ireland; that wanted to hear about Harry's process of Enchanting. More specifically the man was asking how Harry had learned his Enchanting or who from as he'd been absent from the Magical World for so long. It seemed the man believed Harry had either been taught by someone or had somehow created a new form of Enchanting altogether. Harry knew his spell-forging method that he'd taken from a Muggle fantasy novel and tweaked until it worked was a bit different than the standard Enchanting that was in use today. Though he wasn't about to spill the beans on his little secret. He'd just explain that he picked it up from a book and made his own trial and error attempts before getting better at it. That should satisfy the curious Irishman.
The sixth and final letter was from an unknown sender who'd praised Harry for being such a 'smart young Enchanter' and encouraged him to 'keep his curiosity alive and constantly exploring'. From the missive Harry was made aware that this person had been one of the people that purchased one of the four Scouters he'd sold through Owl Order. Whoever had written him had also hinted that they'd keep an eye on his future developments and hoped to one day see Harry as a Master Artificer. Though the person had signed the end of the letter oddly, it was simply a drawing of a circle with symbols and geometric shapes that Harry couldn't make heads or tails of.
"That was a bit odd, but at least they seem supportive of my Enchanting. But do they understand that to be a Master Artificer I'd have to craft seven true Artifacts? There hasn't been a Master Artificer in almost nine hundred years and that was a Chinese mystic that was supported by the ruling dynasty of the time. I somehow doubt I'm going to suddenly be given support by a ruling family so wealthy I'll be able to have any material in the world to work with." Harry mused over the letter and the title of Master Artificer. Making even a single true Artifact could take years or even decades depending on its function. Making seven could easily take a lifetime! With a sigh Harry decided to get his homework assignments out of the way before writing replies to the letters he'd received. Afterwards he'd start his first draft of designs for his personal Runic Safe. He'd prefer to keep his money himself since the Goblins were apparently in the business of extorting their vault holders.
