Quickly, Augustine decided that it was not a good idea to investigate this all by himself, so he decided to give his mentor a call. Silas Baker was a gruff investigator from the Bureau of Misuse of Magic in the UK but was relocated to the American branch some time ago. He was family friends with Agustine, which was how Silas became his mentor.
As he was calling his mentor, the wizard noticed that he was subconsciously stroking his new abs. Augustine grinned and then continued to not so subconsciously stroked them. Even if they were just beginner abs, he still loved feeling the ridges that his stomach now had.
"Hello?" Silas said on the phone, "Augustine? You usually don't call this early. Something up?" Augustine then proceeded to tell his mentor about his experience at the gym, the magic he felt, and the changes he was experiencing. "I see, how strange. Well, from the sounds of it, there's some sort of spell that's passively changing you, and I can tell you now there are no sanctioned experiments going on at that gym. Right, I'll make sure to have someone investigate the gym."
"Wait, allow me to do the investigation first," Augustine suggested. "I've already been exposed to the magic, so I should be the one to investigate to minimize the number of agents exposed to this place. Plus, this is what I've been studying for." Silas paused for a moment, thinking about this before making his decision.
"Alright, but be careful, okay? Remember the procedures I taught you." Augustine agreed and then went about his day.
--------------------------------
Later, Augustine arrived at the gym, a little earlier than he normally would, to begin his investigation. The first thing he did was cast a simple spell to analyze the spell that was cast on the gym. Then he went over to where Bradley was to begin his regularly scheduled personal training session. While he was exercising, Augustine, now actively aware of the magic in this place, could feel the effects that the magic had on his body. Every rep he did, he could feel his muscles becoming a little bigger than they were before. The wizard had to admit it was an intoxicating feeling for sure, but he had to focus on the task at hand.
"Come on, Augustine. Yeah, just like that." For example, Augustine noticed that Bradley was definitely more muscular than when he first met him. The wizard had asked if Brady noticed anything weird about his "Gains," but the personal trainer said there wasn't anything weird going on. How strange, surely a bodybuilder like Brady would notice if he was suddenly gaining more muscle than usual in a short amount of time.
Augustine then proceeded to scan the gym, which was when he noticed a group of people he recalled seeing on his first day here. Except now they were looking quite a bit different than he arrived. One person, who Augustine thought named was Neil, looked like he was some sort of athlete when Augustine recalled that young man looked like a twig before. Then there was the jock that tormented Neil, whose body was changing in the opposite direction than that of Neil. The jock seemed to have lost quite a bit of muscle mass but strangely didn't look too bothered about that. Then there were his two friends, one of them looked oddly tanner than when Augustine first laid eyes on him, the other looked a fair bit older than he did before. Huh, didn't that jock have a third friend in his workout group, Augustine noted. He had to wonder what had happened to that man.
Anyway, after his workout, Augustine cast one final spell. When Bradley had his back turned, Augustine cast a spell to copy the gym's list of members to cross-reference for later.
--------------
Back at Augustine's house, he and Silas were discussing the results of the investigation over the phone. The analysis spell had revealed Sandra's rules for the curse she cast on the gym and a bit more as they found out. The two men had noticed that sex between two gym patrons could also trigger the effects of the curse.
"I have to admit I'm impressed and a little scared of this person," Silas noted. "Usually, a spell like this would be cast with multiple magic users, but it seems like only one person cast this spell. Although I can also tell that they're pretty arrogant, considering they didn't iron out all the kinks in their spell."
"Yeah, I wonder who would cast a spell like this, though," Augustine commented. "I'd assume it would be a gay wizard looking for a boyfriend, but we can't say for sure this early on."
"If that were the case, why go through the trouble of casting a spell on a whole gym?" Silas pondered. "Especially considering unsanctioned spells that cause wide-spreading reality changes are a big no-no here."
"Yeah," Augustine nodded his head in agreement. "Anyway, I'm guessing you're going cross-reference the gym patrons to the list of magic users in the area? In the meantime, I'll keep an eye on the gym for now." That last part confused Silas until he remembered something.
"Oh right, you do prefer men, right?" Augustine was bisexual, but he found himself leaning more towards dating men than women. So, he wasn't exactly bothered by the sexuality changes. Plus, when this was all over, he probably could get the changes reversed if he really wanted to. "Okay, just remember to keep studying. If you have your certifications in a few days and if you pass, you surely will be getting a job here."
That really lit another fire in Augustine Blaise's heart. Not only was he even more motivated to certifications, but also to investigate the gym even more now.
