"Now that I know this works and it didn't get damaged from use I guess I should give this invention a name too." Harry smiled as he looked over the Rune carved stone frame. "Maybe another acronym? It could become my thing." He chortled to himself as he thought it over. After five minutes of thinking he announced his self-scanner's name, at least to himself. "Transfigured Energy Scanning Talisman or T.E.S.T. for short, I wonder if I can market this as well? 'Get your Test Frame and discover your own Magical strength.' Sounds like an acceptable marketing line." Harry chuckled as he set the frame down on the Professor's desk he'd appropriated for his work table. He'd talked to both Penelope and Tonks about possibly starting up an Owl Order business. Even underage children could do business through the Owl Order service. Since Owl Order took care of all business operations and costs of shipping said products with their massive flock of highly trained owls anybody could sell through them. The company took ten percent of the profit as their share but for Harry any money coming in would be worth it.
Penelope's reaction when he'd showed her his Scouter and explained its function had been more than amusing. Tonks had almost fallen over from laughing so hard. But the Prefect had agreed that if he could make enough of them that he'd be practically guaranteed to one day be approached by some big names looking to sponsor him as an Enchanter. That suited Harry just fine, he'd get to continue crafting and honing his skills and one day he'd create a true Artifact and earn the title Artificer. Incidentally Tonks' smug smile at getting her updated mana reading when Penelope got her first was amusing as the two girls playfully jibed at each other over their numbers. Tonks' new reading had gone up to '4776' while Penelope had a reading of '2812'. He'd also learned that Tonks was a Metamorphmagus during the course of the conversation when Penelope had brought it up and the Seventh Year had demonstrated for Harry. That had set his curiosity into overdrive for a few moments and Tonks had laughed herself silly at his multitude of questions. His curiosity had gotten completely derailed however when Tonks had made a lewd innuendo about Harry wanting to 'examine' her. Penelope had scolded the older girl while Harry had tried to hide his furiously blushing face.
Harry chuckled at the memory of his fun loving friend and locked up his practice room, or was it a workshop now? Heading up to Ravenclaw Tower with confirmation that his mana was increasing would see Harry getting a good sleep tonight. Penelope was helping him write up a promotional ad for the sale of his four new Scouters for the Owl Order service. Technically he'd made five but he was keeping the fifth one hidden in his workshop/practice room in case the one he was currently using was ever broken. After discussing it with Tonks, Penelope, and even Hagrid they'd settled on a price of ten Galleons for each Scouter. It was on the high end, price-wise, for an Owl Order item but as soon as people found out it was not only made by Harry Potter but what it was capable of there would be no end of people wanting one.
The next evening the Halloween Feast was in full swing. Decorations were all over the Great Hall and almost everyone was in a festive mood. Harry was sitting between Penelope and Mandy and enjoying the Feast. While it was the anniversary of his parent's deaths he'd never known them and had done what little mourning he was capable of long ago. From the way Hagrid had described his parents to him he was fairly certain that both would rather he enjoy himself with friends on this day instead of mourning them. He could see Tonks over at the Hufflepuff table putting on a show with her Metamorph abilities getting cheers from her House mates. Just over halfway through the Feast Professor Quirrel had barged into the Great Hall screaming about a Troll in the dungeons before promptly falling into a dead faint. The cacophony that had created had taken three loud blasts from Dumbledore's wand to silence. The Headmaster had instructed the various Prefects to lead the rest of the students back to their Common Rooms while the teachers went to deal with the Troll. As the large mass of students began to move Mandy had caught up to Harry and told him of Hermione's absence from the Feast. According to Padma's sister Parvati, an insensitive Gryffindor named Ron Weasley had insulted Hermione and she'd run off crying. Padma and Mandy had both tried to talk Hermione out of the bathroom she'd been holed up in and had only left after Hermione had promised she'd come to the feast later.
"Well shite, I'll try to let a Professor know, go with the others and tell Penelope where I am." Harry told Mandy as he dashed off in the direction the Professors had headed in. Less than a minute later and Harry wasn't sure he'd be able to catch up to the Professors at all. So the next best thing was to go up to the bathroom that Hermione was in and take her to Ravenclaw Tower until the Troll was dealt with. Rushing up the stairs Harry sprinted down the corridors until he almost gagged on the foul stench coming from ahead of him.
"Ack! What the bloody hell is that smell?!" Harry coughed as he rounded the corner to the corridor that Hermione was supposedly in. "Oh right, Trolls are supposed to smell horrible." Harry muttered to himself as he watched the large grey-skinned beast lumber into the bathroom in shock. A moment later a scream tore through the air and Harry was moving before he could think. Shoving the door open Harry was met with the sight of destroyed bathroom stalls and Hermione trying to hide under the sinks. The Troll, Mountain Troll if the books he'd bought on Hagrid's recommendation were correct, turned to look towards the banging door as Harry caught Hermione's eyes.
"Harry?!" Hermione cried out in panic, the Troll slowly turning to look at her again when she yelled.
