The massive door swung shut behind Arthur with a resonant thud that seemed to echo between dimensions. For a heartbeat, darkness enveloped him completely.
Then his eyes adjusted.
He stood in a vast entrance hall that smelled of sandalwood and old paper. Ancient artifacts gleamed in glass cases along the walls, each radiating distinctive energies that tickled his enhanced magical perception. Grand staircases swept upward on either side, their wooden railings polished by centuries of hands.
The London Sanctum felt eerily still compared to the magical buildings he was accustomed to—no moving portraits, no floating candles, no ghosts drifting through walls.
Just silence and watchful shadows.
Arthur's footsteps echoed against marble as he ventured further inside. A floorboard creaked somewhere above, drawing his attention upward.
"Arthur Hayes," a voice called from the top of the staircase.
A tall man in blue robes descended with measured steps. His face bore the weathered look of someone who had seen far more than most, yet his movements remained fluid and precise.
"Yes," Arthur confirmed, hand instinctively hovering near his useless wand.
"I am Master Chen, guardian of the London Sanctum." The man's voice carried a faint accent Arthur couldn't quite place. "The Ancient One is expecting you."
Arthur's eyebrow rose slightly. "Is she now?"
"She has been for some time." Master Chen gestured toward the staircase. "This way. One doesn't keep the Sorcerer Supreme waiting."
Arthur followed him up the curved stairs, past display cases containing objects that radiated power unlike anything in the wizarding world and would have sent most wizards into scholarly frenzies.
At the top floor, they approached an ornate door carved with interlocking circles and spirals that seemed to shift when viewed from different angles.
"Through here," Chen said, pushing the door open. "She awaits within."
Arthur entered a circular chamber unlike anything in the wizarding world. Three massive doorways stood at equal distances around the perimeter, each framed by distinctive architectural elements representing their locations. The air here felt charged, as if currents of invisible energy flowed between the portals.
The door closed behind him with a soft click. Master Chen had not followed.
Arthur stood alone in the chamber, examining the doorways with interest. One clearly led to New York, another to Hong Kong based on their designs. The third, directly across from him, must return to London.
"You are late, Wizard Hayes."
Arthur turned toward the gentle voice. In the center of the room stood a slender woman in yellow robes, her head completely bald, her ageless face serene despite the sharp intelligence in her eyes.
The Ancient One.
Without hesitation, Arthur gave her a respectful half-bow—a gesture he'd shown to almost no one else in this world.
"Sorcerer Supreme," he acknowledged, straightening.
Unlike his interactions with Dumbledore, Fury, or other authority figures, Arthur felt no urge toward his usual detached insolence. This woman had safeguarded reality itself for centuries, making choices and sacrifices few could comprehend. If anyone deserved respect, it was her.
"No need for formalities," she said, her voice carrying a hint of amusement. "Though I must say, I did not expect this reaction from you."
"I'm merely showing respect to the Sorcerer Supreme who has protected this reality from threats most people couldn't begin to comprehend," Arthur replied.
She studied him with eyes that seemed to see far more than his physical presence. "You know a great deal, Mr. Hayes—perhaps more than you should." A small smile played at her lips. "But this isn't the place for such conversation. Please, follow me."
With elegant precision, she traced her fingers through empty air. Golden sparks followed her movements, forming a perfect circle that expanded into a portal. Through it, Arthur glimpsed a simple room with wooden floors and paper screens.
Without looking back to see if he followed, the Ancient One stepped through the portal. After a moment's hesitation, Arthur did the same.
The portal closed behind them with a sound like a sigh. They stood in a tranquil space that felt worlds away from London's urban energy. Low cushions surrounded a simple wooden table where a teapot already steamed. Sunlight filtered through rice-paper screens, and the air carried the faint scent of jasmine and mountain herbs.
"Please," she gestured to a cushion, "sit."
Arthur settled across from her, watching as she poured tea with practiced grace.
"You were expecting me," he said. Not a question.
"Yes." She handed him a ceramic cup, warm against his fingers. "I noticed your presence during the recent Kree incursion."
Arthur's eyebrows rose slightly. "You were there? Observing?"
"I observe many things." She sipped her tea. "That's how I recognized your uniqueness."
"If you were watching, why not intervene?" Arthur asked, the question that had nagged at him for weeks finally finding voice. "Earth was nearly destroyed."
"The Sorcerer Supreme's duty is to guard against mystical and interdimensional threats," she explained, her tone neither defensive nor apologetic. "Not alien invasions or conventional warfare."
"Then whose responsibility is it to protect Earth from those threats?"
"Yours," she said simply. "And others like you who call this planet home."
Arthur frowned. "With respect, that seems like an arbitrary distinction. Danger is danger, regardless of its source."
"Is it?" Her gaze sharpened. "If I intervened in every crisis, what would happen to humanity's capacity to defend itself? To grow beyond its limitations?" She set her cup down with perfect precision. "A child who never faces challenges never develops strength."
"I would have appreciated your intervention nonetheless," Arthur said dryly. "I expected to die that day. If Captain Marvel hadn't arrived when she did, we wouldn't be having this conversation."
"Yet here we are." The Ancient One refilled their cups. "That incident is precisely why I took notice of you, Mr. Hayes. You're quite remarkable. You knew exactly when Carol Danvers would return to Earth. You recognized who I am without introduction." Her eyes met his directly. "How is that possible?"
Arthur considered his response carefully. This was perhaps his only opportunity to speak freely about the burden he carried.
"Before I answer that," he said, "may I ask you something? What exactly do you see when you use the Time Stone? Do you truly see the future?"
If she was surprised by his knowledge of the Eye of Agamotto, she hid it well. "Another piece of knowledge you shouldn't possess," she noted softly. "You grow more interesting by the minute, Arthur Hayes."
"Will you answer my question?"
The Ancient One studied him, seeming to weigh multiple possibilities before responding.
"The future isn't a single fixed path, Mr. Hayes," she finally said. "What the Eye reveals isn't 'the' future, but possibilities—countless branches extending outward from each moment. The smallest change, even just me seeing the future through the Eye, can cascade into entirely different outcomes."
"So there's no single predetermined timeline?"
"In theory, there should be," she acknowledged. "But in practice, with so many forces capable of manipulating time, dimensions, and realities, no future is truly fixed until it becomes the present."
Arthur leaned forward slightly. "But what if someone had knowledge of one specific future? A single timeline that may or may not be this one?"
"What do you mean?"
"I have memories," Arthur said quietly. "Since birth. Memories of events yet to come—a future where I don't exist and there are no wizards like me. Different but still the same in many ways."
He felt strangely relieved to finally share this burden with someone. For the wielder of the Time Stone, knowledge of possible futures shouldn't be shocking. And Arthur found himself wanting, perhaps needing, to tell a part of his secret to someone who might understand.
"My memories are like watching from the outside—seeing everything that will happen."
The Ancient One's expression remained neutral, but her full attention focused on him with almost physical intensity.
"That would be highly unusual," she said carefully. "The most plausible explanation might be that someone traveled backward in time and somehow imprinted their memories into you. Such things have happened before."
"So what happens now?" Arthur asked. "Am I considered a threat to the natural order? Are you going to wipe my memories?"
A hint of amusement touched her lips. "What makes you think that?"
"My intervention nearly destroyed Earth," Arthur pointed out. "In my memories, Carol Danvers handled the Kree threat alone. The planet was never endangered."
"Yet everything resolved itself, didn't it?" She poured more tea with steady hands. "I don't make a habit of interfering with the natural flow of events, Mr. Hayes—even when that flow includes someone with knowledge of possible futures."
She smiled faintly. "If I did, I would have my hands perpetually full. And as you noted, this world runs differently than you remember. It has wizards. So things might not always proceed as you expect, Mr. Hayes."
"That's surprisingly reassuring," Arthur admitted. "Had I known that, I might have visited this place earlier."
"Perhaps the time wasn't right until now." The Ancient One set her empty cup down with finality. "Now that we've addressed your concerns, I believe you came here with more than philosophical questions."
"I did," Arthur confirmed. "I'm interested in learning sorcery."
"The mystical arts," she corrected, her eyes reflecting something between amusement and interest. "And that, Arthur Hayes, may prove more challenging than you anticipate."
