It was 500 years since the incident with the shifters. After they went home, they had made friends amongst each other.

The elvish council had given permission to the demigods to visit lost cities, partly after knowing about their 'creation' by gods, but mostly because the demigods kept coming anyways.

They had taken Percy to talk with Silveny (he said he preferred Arion's cussing rather than her screaming ) Percy, Keefe, Leo, Stolls and Dex  had come up with a lot of pranks.

They had a good tour of the camp half blood (Sophie said it was the best of a fangirls dream).

They had taken the demigods on a tour of Lost cities.

The demigods helped in their silent war against neverseen. Be it giving a helping hand to Elwin by Will, or be it training sessions with Tam and Nico, Linh and Percy, Marella and Leo, etc.

Thalia, and eventually Reyna had been heartbroken when the demigods died, one by one. But the elves had been there to support them with everything. 

The elves were invited to Percy and Annabeth's wedding. Leo and Calypso, Hazel and Frank, Jason and Piper also invited them to their weddings.

Elves extended the same courtesy to them too, but Elvish weddings were a lot grander (and a hell lot weirder).

As the years passed, both the sets of heroes had families, and the demigods eventually died in peace. The kids of the demigods always remembered the elves as the cool godparents that never aged, until they were mature enough to make sense of the elvish world.

All in all, all's well that ends well.

And now, in the further chapters, I will tell you all about it in detail, what happened, when happened and how it happened.
