1. Fic starts towards the end of the battle of new York when tony flies the nuke through the portal
2. He finds that some children are aboard the chutari? ship? Not sure who the kids were held by.
3. I almost want to say it was a mild guardians of the galaxy crossover.
4. Tony brings the kids back to earth and begins raising them as his own.
5. I think it eventually becomes Tony/Loki
Thanks so much in advance. Help if you can!
