The X-Mansion also possessed Sentinel robots under their control, but those were merely the crudest first-generation models, armed only with basic firearms and reliant on jet engines for flight, scarcely different from unmanned drones.

These primitive machines could never compare to the second-generation Sentinels, which had undergone biological upgrades, boasting stronger bodies and mutant abilities.

Even less could they rival the Original Sentinels, crafted exclusively by the Debarli, of which only four existed.

"Cease operations, conserve energy," Sebastian commanded.

At his order, the two Original Sentinels immediately powered down, standing motionless.

Their power source was a remarkable bio-battery, engineered to mimic mutant abilities.

Though not as advanced as Tony's Arc Reactor, it sufficed to keep the Sentinels operational for extended periods.

Observing the now-inactive Sentinels, Sebastian stored them in his Pouch, which, thanks to multiple Extension Charms, had an impressively spacious capacity.

With a wave of his wand, casting Reducto, Sebastian completely demolished the core area with a blast, then swiftly opened a portal and stepped through, arriving at Charles and the others' side.

As he emerged from the portal, Sebastian caught sight of an Original Sentinel, nearly dismantled, its parts strewn about.

The sight made his eye twitch, akin to the feeling of watching a prized collectible destroyed by a mischievous child visiting his home, forced to smile outwardly for the sake of politeness while inwardly cursing with a torrent of frustration.

Worse still, to avoid upsetting the others, Sebastian couldn't show his irritation.

He waved his wand, casting Reducto to shatter the Sentinel's core, ensuring the remaining parts stayed as intact as possible, then stored the broken machine with a flick of his hand.

Noticing the Sentinel vanish, Logan, who had been tearing it apart, turned with bloodshot eyes toward Sebastian.

Recognizing him, Logan exhaled heavily, regaining his composure.

While elite mutants could resist regular Sentinels with manageable losses, facing an Original Sentinel had proven catastrophic.

Approximately a dozen mutants had perished, and twenty to thirty more were injured.

Among the X-Men, Hank and Raven had sustained severe wounds, both now unconscious.

Charles and Erik were visibly exhausted, particularly Erik, who, as the primary attacker, looked on the verge of collapsing into sleep at any moment.

Sebastian hurried to Hank and Raven's side.

As close-combat mutants, they had borne the brunt of the battle.

Most of the dead were melee fighters. Only Logan's extraordinary healing factor and Adamantium skeleton had kept him alive, though without them, he might have died multiple times.

Seeing Sebastian arrive, Charles, now bald, grabbed his arm with reddened eyes and pleaded, "Sebastian, save Hank and Raven. You must have a way, right?"

"I'll try!" Sebastian replied.

Crouching down, Sebastian examined their injuries. Hank's were the gravest, with a horrific penetrating wound through his chest. Raven's injuries were also severe but comparatively less critical.

As Sebastian prepared to treat Hank, Hank weakly grasped his hand, his voice barely audible, saying, "Save Raven first, save Raven first!"

"Relax, neither of you will die!" Sebastian assured them.

Before Hank could speak again, Sebastian cast a weakened Stupefy to put him to sleep, then retrieved four syringes from his Pouch, each containing a specially crafted potion, and injected two into each of Hank and Raven's bodies.

Immediately, their wounds began to heal visibly, showing clear signs of recovery.

However, the potions alone were too slow, requiring additional magic to enhance their effect.

White light radiated from the tip of Sebastian's wand, spreading over Hank and Raven, then rippling outward. Everyone touched by this light, bolstered by Episkey and Vulnera Sanentur, experienced some degree of relief and recovery from their injuries.

"Erik, I have more potions here. Prioritize the severely injured: one full dose for fatal wounds, half for non-lethal ones, and none for minor injuries. Supplies are limited," Sebastian instructed.

He tossed the last ten syringes, which Erik caught with his magnetic powers, suspending them in midair.

Looking at Sebastian, Erik said earnestly, "Thank you. I owe you a big favor."

"Go save people. You're not escaping this debt—I've noted it," Sebastian replied with a nod.

With that, Sebastian focused on treating Hank and Raven, allowing his magic to ripple outward to provide some relief to others, ensuring their wounds wouldn't worsen.

Maintaining such large-scale magic with his remaining energy was immensely taxing for Sebastian.

After over ten minutes, Hank and Raven's conditions finally stabilized.

Seeing them sleeping peacefully with steady breathing,

Sebastian collapsed onto the ground, exhaling in relief.

"Charles, I didn't get a chance to ask earlier—what happened to your head? One moment they are flourishing as garden, and now your hair's completely missing," Sebastian remarked, catching his breath.

Hearing Sebastian's question and seeing Hank and Raven safe, Charles managed a faint smile. "During the battle, we faced mutant attacks from the military, including a telepath. I fought him mentally while coordinating orders for the others. The strain was too much, and all my hair fell out," he explained.

In the original timeline, Charles's baldness resulted from Apocalypse possessing his body.

Sebastian's intervention prevented that, preserving Charles's thick hair for years.

Yet, history's wheels were relentless, and Charles, after retaining his hair for three extra years, had finally gone bald.

"Charles, once this is over, the President will declare the Sentinel program a failure, deeming it a violation of human rights, and he'll expose the Debarli's involvement.

With about two years left in this President's term, you can use that time to elevate the status of mutants.

While it won't erase public prejudice entirely, with the President's cooperation, you should be able to distinguish between good and bad mutants, ensuring situations like this don't happen again," Sebastian outlined.

"The President… Sebastian, did you manipulate the President?" Charles asked, his tone wary.

"Charles, sometimes you can't afford to be soft-hearted. Besides, I didn't kill him—I only controlled him with Imperio. If you wish, I can restore him to his former self," Sebastian replied calmly.

-------------

Sebastian chose not to mention the Phoenix Force to Charles and the others yet, for according to Wok's memories, although it had entered the solar system, its approach was relatively slow, destined to visit each of the nine planets in sequence.

Indeed, in this world and era, Pluto was still considered one of the nine planets.

Thus, the Phoenix Force's arrival on Earth would take at least two to three years.

For the long-lived Debarli, this was a brief span, but for humans, two to three years could bring significant change.

Sebastian couldn't linger in this world for that long. Moreover, even if the Phoenix Force arrived now, he knew it would bond with Jean Grey.

But what then? In the face of the Phoenix Force, even Dormammu paled in comparison, let alone Sebastian himself.

-------

With the combined efforts of Sebastian, Erik, Jean, and other mutants, the X-Mansion was rebuilt, rising anew from its ruins.

Three days had passed since the destruction of the Sentinel underground institute.

Under Sebastian's influence, the President declared the Sentinel program illegal, citing the Debarli evidence.

Though the evidence wasn't fully disclosed to the public, it was sufficient to force the White House to abandon the program entirely.

After all, mutants, with their intricate ties to humanity, were far closer kin than malicious alien Debarli.

In the aftermath, to address the remaining Debarli, the President met with Charles.

Together, they formed a special task force comprising soldiers less hostile to mutants and select X-Men, dedicated to investigating and capturing Debarli fugitives across the United States.

They regularly filmed these operations, broadcasting them at fixed times to show the public that mutants weren't all threats—they could be humanity's protectors.

Later, humans and X-Men formed teams to pursue criminal mutants, but that was a future matter, no longer Sebastian's concern.

"Charles, the rest is up to you. I've entrusted the President's soul crystal to Raven.

With her blend of your compassion and Erik's decisiveness, I believe Raven is the best person to hold it," Sebastian said.

In Sebastian's view, the ideal leader for mutants was neither Charles nor Erik but Raven.

As he noted, Raven possessed Charles's compassion and Erik's resolve.

She championed peace yet wielded decisive force when needed, embodying the best of both men. Raven was truly an exceptional leader.

It was a pity that her mutant abilities weren't particularly outstanding, or she might have outshone Charles and Erik entirely.

Charles glanced at Raven, who stuck out her tongue playfully, and shook his head with a smile. "This works. Otherwise, I might've been too soft-hearted and destroyed the soul crystal entirely. But honestly, as long as Erik doesn't get it, anyone else is fine," he said.

At Charles's words, Erik rolled his eyes but didn't argue.

Deep down, he knew that if he held the President's soul crystal, things could spiral out of control.

Turning to Erik, Sebastian asked, "Erik, what are your plans next?"

"I'll build a nation for mutants. The U.S. government granted us a small island, and we plan to turn it into a mutant homeland, where we can live freely," Erik replied.

"That sounds good. Next time I visit, I'll definitely stop by," Sebastian said.

"Next time you come, it'll probably be years later, right?" Erik asked.

"About two or three years, I'd guess. I'll return then," Sebastian confirmed.

Looking at Sebastian, Erik hesitated before saying, "Sebastian, take care of those siblings for me."

At this, a trace of embarrassment crossed Sebastian's face, as you all know which siblings they are and What happened to them.

He cleared his throat, nodded to Erik, and said no more. Raising his left hand, he activated the Space Stone's power, transforming into a streak of blue starlight that shot skyward, vanishing from their sight.
