--Avengers Headquarters--

"What the hell is that?" Quill said, looking up the sky.

There was what seemed to be an explosion in the sky. But it was not near Earth, it was farther into space.

"Should we check on it?" Gamora asked.

"We will, once Rocket finishes with those bombs."

"I'm almost done. Just give me a few more minutes." Rocket said, putting some gas into the bomb.

"Do you think it will explode once it hits a surface?" Bruce asked, as he and Tony stood there watching.

"And done, it will explode upon impact. Watch this." Rocket said, throwing the bomb out the broken window.

Soon, gas appeared from the window while Bruce stood in amazement.

"You could've thrown it somewhere else." Tony said.

"That will do. What were you calling me for, Quill?"

"You see that?" Quill asked, pointing at the explosion in space.

"Yeah, what's so interesting?"

"C'mon, Rocket, there's an explosion in space."

"We have to check it out." Gamora said.

"Fine, get your gear ready. We're going in a few hours."

"We have to wait for Steve's plan first." Tony said.

"Steve again, and again, is he your baby sitter?"

"No, but he is a leader."

Soon, a taxi arrived outside the headquarters and a boy walked up the stairs.

"Mr. Stark, Mr. Stark." Peter said repeatedly.

"Why'd you go here, kid?" Tony asked.

"I saw this big space ship, and there were aliens there, and there were heroes fighting, it was crazy."

"Who were the heroes?"

"I saw the Avengers there, but there was these other heroes."

"Was it those guys, the Defenders?"

"I think so."

"Hey, Tony, we got fifteen bombs here. Want to bring them all?" Bruce asked.

"Sure, we need all the firepower we can get. Now, we just have to think of a plan to get to space."

"Milano is damage; those Skrulls shot it while were fighting." Rocket said.

"I think some of the bullets you shot hit the Milano." Quill said, looking at Rocket.

"I was having the time of my life."

"You've got to be kidding me."

"Oh, I'm not Quill, it was the happiest time of my life. Right, Groot?"

"I am Groot." Groot said.

"See, he agrees with me."

"Guys, there are more explosions now." Peter said, looking at the sky.

"What the hell is going on up there?" Quill turned.

"Who do you think is up there causing that destruction?" Drax asked

"Thanos." Nebula said, everyone looking at her.

"How do you know?" Tony asked.

"Isn't it obvious?"

--London Sanctum--

"What do we do now?" Scott asked.

"We think of a new plan,. What will be our next move?" Strange said, as the group walked through the hallways.

"What is this place?" Wanda asked.

"One of the 4 Sanctums. The places where these Sanctums are located are: Kamar-Taj; Hong Kong; London, where we are now; and America, the one that just got destroyed by those aliens." Strange said.

The group walked into a meeting place, similar to the one they were in before.

"So, I say we have to regroup with them, through flight, I guess." Scott suggested.

"That will take too long." Natasha said.

"I got that part of traveling, I just need to rest for a few hours." Strange said.

"Why can't we  just go now?" Steve asked.

"Because, if we open my portal, maybe there are more of those aliens that will greet us."

"Does anyone have some sort of walkie talkie?" Scott asked.

"No, and why do we need that?" Wanda asked.

"You know, so we could contact Tony or something."

"I feel something, destruction is being done throughout the universe." Thor said.

"Is it Dormammu, or even Galactus?" Strange said.

"I feel the power of the stones combined."

"I forgot. We have books here, follow me." Strange said, walking to the library.

"Does every Sanctum have a library?" Steve asked.

"Yes, but the one that provides the most information is the Sanctum in Kamar-Taj."

They went inside to the library which was filled with many ancient books. Everyone but Strange was amazed, so many books about mystic or ancient beings and powers.

"These people must be very powerful." Scott said, touching one of the books.

"Not powerful. Those who are powerful are evil, like Dormammu."

"Who is Dormammu?" Natasha asked.

"A great story, for another time."

Strange got a book from one of the shelves and placed it on the reading table.

"So you have a book about?" Thor asked.

"The Infinity Stones. I saw this book before, I just didn't have the time to read it."

"What are you interested about with the book?" Wanda asked.

"Here, page 682, if the stones are in possession by a living being, it will cause mass destruction throughout the universe."

"We have to call Tony." Steve said.

"Aren't there those telephone booths here in London?" Scott provided helpfully.

Everyone went out the library and looked for a door. They opened it and tried to find a telephone booth, instead greeted by a person.

"What are you doing here?" Thor asked.

"Glad to see you again, brother." Loki said, smiling.
