Trust, Such a Fragile Little Thing

Ok, so, For we once so loved the world is not my story. It is a story written by HowlingDarkness95, at this link:
https://www.fanfiction.net/s/9937571/1/For-We-Once-So-Loved-The-World
It is completed, and the author has not had any sequel mentions, so I'm trying my best here because, oh, I just so hate this hanging.
This should be viewed not precisely as a sequel but more of a fanfiction of For we once so loved the world.
So, I'll try my best, and it most probably would not match up to anything like the way HowlingDarkness writes because he (he? I'm not sure) is brilliant, and I'm just trying my best.

There would probably be less of the Avengers (because I don't know much about them, not really...) and more of Percy and Loki and the Greek Pantheon.

Enough talking; let's get to it already.

---
Loki's punishment for his betrayal to the Nine Realms was spending a hundred years in each realm, Asgard, Midgard, and Jotunheim, repairing the damage done by the war. While he could have argued, debated, even pleaded for a better judgment, he agreed to this absurd request.
Because he could never forget the boy who was so angry, so tired, so... utterly heartbroken as Percy Jackson had been, and there was no way that he could leave the boy like that.
He was given a choice, which realm did he want to go to first?
There was no hesitation on the God of Mischief's behalf.
"Midgard."
