We are in the Endgame now

We all knew that the Endgame started now
And that there was also no going back
The heroes needed to beat him somehow
But the power is something that they lack

They figured that they needed the six stones
To keep the almighty Thanos away
And they all had a feeling in their bones
That this plan was going to go their way

So they traveled all the way back in time
To retrieve the six stones that they had lost
An epic battle began at daytime
The heroes won the fight, but at what cost?

With a snap, Tony Stark had lost his life
Then, he was knocked into the afterlife
