Skirmish in the Dark Dimension

"Dormammu, I've come to bargain." "You cannot do this forever." "Actually, I can. This is how things are now. You and me. Trapped in this moment. Endlessly." "Then you will spend eternity dying." "Yeah. But everyone on Earth will live."

- Doctor Strange and Dormammu

The Skirmish in the Dark Dimension was the first and final confrontation between Doctor Strange and Dormammu.

Background
"Temporal manipulations can create branches in time. Unstable dimensional openings, spatial paradoxes, time loops! You want to get stuck experiencing the same moment over and over again forever, or never having existed at all?" "They really should put the warnings before this stuff."

- Karl Mordo and Doctor Strange

Having destroyed the London Sanctum and attacked the New York Sanctum, Kaecilius and the Zealots launched their final attack on the Hong Kong Sanctum. They found the sanctum protected by Wong and the Masters of the Mystic Arts. Wong was killed in the resulting battle and the Hong Kong Sanctum was destroyed. With the final sanctum destroyed, Dormammu began to absorb Earth into the Dark Dimension.

Using the power of the Eye of Agamotto, Doctor Strange was able to reverse time, bring Wong back and restoring the Hong Kong Sanctum. Kaecilius returned and confronted Strange, telling him that his actions were useless. Upon hearing from Kaecilius that the Dark Dimension was "beyond time", Strange figured out a way to defeat Dormammu and headed directly into the Dark Dimension.

Battle
"Dormammu! I've come to bargain." "You've come to die. Your world is now my world, like all worlds." "Dormammu! I've come to bargain." "You've come to die. Your world is now my world... What is this? Illusion?" "No, this is real." "Good." "Dormammu! I've come to bargain." "You... what is happening?!""

- Doctor Strange and Dormammu

Entering the Dark Dimension, Strange came across Dormammu, who manifested as a warped version of the former neurosurgeon's face, and stated that he had come to bargain. Claiming that he had come to die, the entity killed Strange only to watch as he came back to life and repeated his previous statement. While confused, Dormammu killed Strange again only for him to reappear. Strange proceeded to explain that he used the Eye of Agamotto to create a time loop that trapped them in the same moment.

Dormammu warned Strange he would suffer for eternity, to which Strange accepted. After killing Strange several times only to watch the loop reset, the desperate entity begged Strange to release him from the loop.

Strange refused, firmly stating that he had come to bargain, and promised to break the loop on the condition that Dormammu put an end to his conquest and take the Zealots with him. The entity agreed to the demands, prompting Strange to leave the dimension and return to the battle.

The Bill Comes Due
"You still think there will be no consequences, Strange? No price to pay? We broke our rules. Just like her. The bill comes due. Always!"

- Karl Mordo

Returning to Earth, Strange watched as the remaining Zealots were turned into Mindless Ones and transported to the Dark Dimension. Strange proceeded to reactivate the Eye of Agamotto and finish restoring the Sanctum before allowing time to resume.

As Strange and Wong began celebrating their victory, Mordo began comparing Strange's abuse of power to the Ancient One's actions, blaming the Masters for the world's imbalances. He then stated that the bill would come due for them all and walked away from his former allies.

The New Protector
"Word of the Ancient One's death will spread through the Multiverse. The Earth has no Sorcerer Supreme to defend it. We must be ready."

- Wong to Doctor Strange

Sometime later, Strange realized he was not ready to harness the Eye of Agamotto and brought it back to Kamar-Taj. Wong agreed with his decision before noting that the New York Sanctum still needed a new protector and that Earth was now vulnerable to interdimensional threats.

Stating that the Masters would be ready to face said threats, Strange returned to New York City and began serving as protector of the New York Sanctum.

Too Many Sorcerers
"Why are you doing this?" "Because I see, at long last, what's wrong with the world."

- Jonathan Pangborn and Karl Mordo

Several months later, Mordo tracked down Jonathan Pangborn and accused him of manipulating magic in order to continue healing his paralysis.

When Pangborn, who claimed he was using his own power, attacked him with a crowbar, Mordo easily overpowered his former ally before stripping him of his powers and causing his paralysis to return.
