"You want to learn invisibility magic? A wise choice—it's one of the most practical spells you can master."
Hearing Aaron's request, Frigga immediately shifted into teaching mode.
"Invisibility magic, much like illusion magic, is a form of auxiliary sorcery. But don't underestimate it. Mastering it can turn you into a ghost on the battlefield. In terms of utility, it's just as formidable as illusion magic."
"Given your expertise in illusions, I'm sure you can already imagine how invaluable invisibility magic can be."
Aaron nodded. He was well aware of how terrifyingly effective invisibility could be.
Loki had used it countless times—boldly attempting to lift Mjolnir right under S.H.I.E.L.D.'s watchful eyes and constantly pairing it with illusion spells to fool Thor and the others. If Loki weren't so comedic, often forgetting to use his magic at the right moment, he'd never have been caught off guard so often. At the very least, he wouldn't have taken so many beatings—he'd have escaped every time.
Even old Loki had faked his own death to deceive Thanos, a feat achieved through the perfect blend of illusion and invisibility magic.
"Once you master invisibility, you'll be able to vanish from sight, fooling even the sharpest eyes," Frigga continued.
"But if you take it further—if you truly refine your skill—you can erase all traces of yourself. Your scent, body heat, even the most advanced technology won't be able to detect you."
"Aaron, I assume you're familiar with Heimdall's all-seeing eye?"
Aaron nodded. "I am. His all-seeing eye can find anyone, anywhere. It pierces through all disguises until he locates his target."
Heimdall's power was, in many ways, absurdly overpowered. Combined with the Bifrost, it granted Asgard a nearly omnipotent presence over the Nine Realms.
Through Heimdall's vision, Asgard could uncover secrets without ever setting foot beyond its borders, ensuring its dominance and maintaining peace.
"His all-seeing eye is formidable," Frigga admitted, "but—" she paused for emphasis, "—it can be deceived by invisibility magic."
Aaron wasn't surprised.
Loki had done it multiple times.
Otherwise, how else would he have conspired with the Frost Giants without Heimdall ever noticing?
Even the Dark Elves' stealth technology had nearly slipped past Heimdall's watchful gaze. Nearly—but not quite. Unlike Loki's perfected invisibility, their method had its flaws, which Heimdall ultimately detected.
"Speaking of invisibility magic," Frigga continued, "Loki is particularly adept at it. Loki, why don't you demonstrate for Aaron?"
She gestured for Loki to step forward.
At the moment, only Aaron, Loki, and Frigga remained in the room. Irene had left earlier, knowing it was inappropriate to linger when the Queen herself was teaching.
Loki had originally stayed behind just to observe.
He had heard the rumors about Aaron's unnatural talent for magic but had never witnessed it firsthand. Now, he was eager to see if the boy truly lived up to the hype.
At Frigga's request, Loki sighed, rolling his eyes, but stepped forward. With a flick of his wrist, he vanished into thin air.
Aaron's eyes narrowed as he focused, trying to detect Loki's presence. But it was useless—his eyes, ears, and even sense of smell failed him.
Magic was the only possible way to track him.
Standard technology would be completely ineffective.
Loki smirked invisibly as he watched Aaron struggle.
Magic prodigy, huh? Let's see how you deal with this.
Loki prided himself on being Asgard's foremost expert in invisibility.
He could fool Thor. He could fool Frigga. Perhaps only Odin could see through his stealth without additional means.
Now, watching Aaron search fruitlessly, Loki's mischievous streak kicked in. Silently, he moved closer, preparing to give the magic genius a little scare.
He had perfected the art of stealth—not just visually, but physically. His footsteps made no discernible sound. There was no disturbance in the dust, no shift in the air.
He was undetectable.
Or so he thought.
Sensing the trickster's nature, Aaron took preemptive action. He activated his Psychokinesis, summoning an invisible wind to swirl around him.
Within that wind, an obstruction formed—human-shaped and eerily distinct.
Aaron smirked.
Loki, realizing he had been exposed, scowled and reluctantly revealed himself.
Frigga chuckled. "Using psychokinetic currents to detect hidden figures—clever. But remember, Aaron, that only works when you suspect someone is using invisibility."
"If an enemy conceals themselves without your knowledge, you won't have the chance to react in time."
"You can't rely on Psychokinesis all the time," she warned. "That's the true strength of invisibility magic—it thrives on unpredictability."
Aaron nodded, taking her words to heart.
For now, she was right. While he could think of ways to detect invisibility, most of them required prior suspicion.
Enemies wouldn't announce when they were hiding.
But he also knew that as his magic grew stronger, he'd find ways to counter that weakness.
Still, his main goal in learning invisibility wasn't for assassination or espionage.
It was to ensure that, if necessary, he could hide—even from the Frost Giants, even from Odin.
And that made it one of the most crucial skills in his arsenal.
Frigga wasted no time. She began explaining the fundamentals of invisibility magic in detail. Her ability to teach was remarkable, her guidance precise.
But for Aaron, the quality of instruction hardly mattered.
Because—
[You cast Invisibility Magic seriously once. You gain a small increase. Invisibility Magic proficiency +1.]
[You cast Invisibility Magic again…]
Before their eyes, Aaron began flickering in and out of sight, rapidly improving his control.
At Level 1, his invisibility was riddled with flaws. His body vanished, but his clothes remained visible—an amusing yet impractical sight.
At Level 2, he refined his technique. Both body and clothing disappeared seamlessly.
At Level 3, Loki's smirk faded.
He could no longer spot the flaws.
Loki, an expert in invisibility, had always been able to detect others using his own understanding of the spell. But now, even he struggled to pinpoint Aaron's presence.
At Level 4, Loki's expression darkened.
Aaron's invisibility was flawless.
If he didn't already know Aaron was there, he wouldn't have suspected a thing.
Loki finally understood why Amora and Irene had both been left questioning reality after teaching Aaron magic.
This kid is unnatural.
By the time Frigga and Loki left, Aaron remained in the classroom, fully engrossed in his training.
Hours passed.
His invisibility magic reached Level 5.
And then—
[You have cast Invisibility Magic with great focus. You gain significant improvement. Invisibility Magic proficiency +4. Your Invisibility Magic has evolved—Group Stealth Magic unlocked.]
Aaron exhaled slowly, feeling the shift in his power.
Not only could he now turn invisible—
He could take others with him.
