It's been few days since Roy started studying in Hogwarts classes. The next week products also arrived. And Roy only bought few things he can use and ignored the trash.
[ Mana Growth Potion, price : £30 (6 galleons or 6 points) ]
[ Alchemy Magic guide (from dummies to masters), price : £100 (20 galleons or 20 points) ]
[ Scented candles recipe, Price : £5 ]
[ Marauder's map, Price : £15 ]
[ Wonder woman's glasses (DC), Price : £1 ]
Yeah, he ignored the last one. As for others he bought them all. Why he bought a useless recipe you ask? It gave him a business idea. Since the enchantment magic is only temporary and works for few weeks or months at most. He decided to use the recipe and enchant the candles with his magic.
As for permanent enchantment it's possible by using more mana and few other materials. He needs to engraved runes on the items. He don't have mana reserves like Loki who has the lineage of frost giants and grew with Frigga who taught him magic. He will apply the enchantments to calm mind, pleasant feeling and purification to it.
He made few samples but didn't sell them instead he used them for himself others are around. Especially those girls from rich families they immediately brought the scented candles after knowing what they are. Some even appeared form Slytherin. Pansy Parkinson is one of them, Daphne Greengrass too. Surprisingly Cassandra also bought the candles but she still has the grudging look at him.
In the past few days she is defeated almost 10 times in a row. So it's understandable, the blow to her pride is huge. And each time she is almost on the verge of tears by the time the duel is finished. It's not only popular among students now, but also the professors. Flitwick himself bought two of them, McGonagall bought one, Sprout bought one too, as for Snape he didn't even show himself at Hogwarts after classes. Of course, at first the professors opposed the sales but Roy visited Dumbledore's office and explained about his new product. In the end after some persuation and the promise to send the old man some candles and also socks enchanted with temperature modulation for Christmas he agreed.
Headmaster's office :
" So what do you think of Mr Miller and his inventions these few days ", Dumbledore asked with a calm look on his face.
" It's brilliant. I don't know how he come up with ideas like these. Although the enchantments are only temporary, they're working very fine. Not mention in the market things like this cost so much", Flitwick said with a smile.
" Although his products are good but maybe we should do something Albus. Afterall he is a child. What if something goes wrong ", McGonagall said.
" But they're working fine right. The candles he gave me are very good. The scent of flowers and lush grass feels so natural ", Sprout said.
" Heh, it's just a simple enchantment. What's so great about it? ", Snape sneered.
" What's so great about it is that there isn't a single rune on them and they are not made from magical ingredients either. It's just a scented candle that muggle uses but somehow enchanted with effects ", Dumbledore said.
He is intrigued by the this unique enchantment. He tried deciphering the secret behind and even once used legilimancy on Roy. Buf failed, Roy cast a glance at Dumbledore at that time with a serious look. Dumbledore decided to observe him for a while before making a move. Afterall he has a PTSD from the two dark lords, he don't want another rampaging through the wizarding world.
In his mind guiding talented young wizards and correcting their path no matter what cost it is, will be the best option. it is all for the greater good. Because Roy's past ring a few alarms in his mind. Orphan, talented, genius, can use magic that surpass his peers. That sounds very similar to Dumbledore.
Dumbledore prayed Roy won't end up like Tom Riddle. He knew how many attrocities and sins Tom Riddle commited in his quest for power. He didn't even hesitate to kill a newborn child. Dumbledore is very vigilant since then, he is trying his best to keep young wizards and witches in Hogwarts away from the influence of dark forces and even removed many kinds of dark arts from the restricted section that are horrifying to say the least.
