Why was Ancient One killed by Kaecilius?
Because she 'saw' Doctor Strange's potential and 'saw' that he was the best successor.
Only if she died could Doctor Strange grow quickly and take on the responsibility of the Sorcerer Supreme.
She might have known that Kaecilius would betray her long ago, but because this was the best outcome, she didn't stop him.
Otherwise, with Ancient One's strength, how could Kaecilius possibly escape from Kamar-Taj?
After all, Kaecilius wasn't alone when he left; he had quite a few followers with him.
If Ancient One couldn't even notice such a big commotion, what was she defending the Multiverse for, protecting Earth for a hammer!
So Ancient One's fate was actually also 'controlled', but she accepted this 'result' and chose to embrace it.
Ancient One was so powerful, yet her fate was controlled by 'mortals' like the Time Variance Authority and He Who Remains. At first glance, it seems a bit absurd.
After all, everyone in the Time Variance Authority is just ordinary people, and He Who Remains was even stabbed to death by Female Loki Sylvie with one knife.
As for Ancient One's strength, there's no need to elaborate too much.
To put it simply, Ancient One wasn't strong enough.
There are countless Ancient Ones in countless parallel Universes and timelines. Although they can access the Multiverse, they cannot access the core of the Multiverse!
In contrast, He Who Remains, a variant of Kang the Conqueror, triggered a Multiverse war a long, long time ago, eventually winning and merging the timelines of the Multiverse, controlling the Multiverse through the sacred timeline.
Although he had a mortal body, he was one of the core lives of the Multiverse.
Core lives are the cornerstone of the Multiverse, extremely few in number, and have the crucial ability to influence the Multiverse.
According to the Observer, there are a total of four cores: Sesnick, Wizard Merlin, Kang the Conqueror, and Scarlet Witch.
Just looking at Kang the Conqueror and Scarlet Witch, one ruled the Multiverse, and the other broke the rule of the Multiverse.
Core lives, their significance is evident.
Although it is said that Female Loki Sylvie killed He Who Remains, stabbing out the Multiverse with one knife.
In reality, even before she killed He Who Remains, the Multiverse had already changed, and the loop of the sacred timeline had already been broken.
And this time coincided exactly with Wanda officially becoming the Scarlet Witch and practicing dark magic. The two events were simultaneous, not a second apart!
Samuel wasn't sure whether it was Female Loki Sylvie or Scarlet Witch Wanda who opened the Multiverse.
It's even possible that it was Doctor Strange who cast the spell to make everyone forget Spider-Man's true identity who opened the Multiverse.
But one thing he could be sure of was that Ancient One likely didn't know as much as he did.
After all, the future Ancient One could see was at most the future He Who Remains could see.
And he could see futures that He Who Remains couldn't even see!
Ancient One knowing that she would become the Void Lord in the future was most likely because when she explored others, she incidentally learned about the Void and his identity.
If she could directly explore the Void, she wouldn't have been so surprised that she might have been pruned and appeared in the Void.
"Have you been to the Void?" Samuel asked with a smile.
Ancient One shook her head.
"Then how are you sure you haven't been pruned by the Time Variance Authority?"
"Time Variance Authority, so that's what it's called."
Good heavens, I can only exclaim good heavens!
Ancient One actually doesn't know the name of the Time Variance Authority?
Samuel relaxed even more: "Do you know why I came?
I have a Time Stone, the Time Stone from this timeline!"
Ancient One was very surprised that two Time Stones appeared at the same time, but she is after all the Sorcerer Supreme, a master of time.
After the surprise, she quickly reacted: "You want to learn the Time Magic in ""The Book of Cagliostro""?"
Samuel shrugged, noncommittal.
Ancient One was a little curious why Samuel didn't learn from the other 'himself' in the Void, since he had already learned Mirror Dimension.
"I can lend you ""The Book of Cagliostro"", but only at Kamar-Taj, you know, it concerns the future."
If ""The Book of Cagliostro"" is not at Kamar-Taj, Kaecilius won't be able to summon Dormammu through the black magic in the book.
"Maybe next time, right now I'm more interested in experiencing your magic."
"Okay!"
Ancient One smiled kindly, her right foot lightly tapping the ground.
In an instant, the ground rolled towards him like falling dominoes.
Samuel leaped to dodge, and the system prompt sounded accordingly.
"Ding!"
"Combat detected, drop reward: Setorak's Crimson Bands (Ancient One)"
It's also Crimson Bands of Cyttorak, the one controlling Ximeizi is a magic item, this one is magic!
Ancient One gracefully and elegantly came before Samuel, the fan-shaped Ring of the Living Tribunal sharply stabbing towards his shoulder.
"Bang!"
Samuel's shoulder tilted slightly back, revealing a roguish smile towards Ancient One.
"Is that all?"
Ancient One smiled, and with the Ring of the Living Tribunal in both hands, unleashed a combo attack on Samuel.
"Bang bang bang -- bang bang bang --"
The two exchanged blows, fighting fiercely.
