A/N Thanks for all the reviews, I'll tie up the story here. This was never going to be a full imagining of the Mark of Athena, but was originally going to be just the Reunion. Thanks to everyone who read this fic.

Epilogue
Annabeth
Annabeth sighed as she walked back onto the Argo II. Looking back at the farewell, it struck her just how much of a miracle it was to see Greeks and Romans side by side, and Amazons, Hunters, and male heroes not fighting each other. It was night, as agreed, and the mood seemed somber when only lit by various torches, and everyone moving around on the silence of night, not one of them wanting to break the spell. She also noted how she seemed to be the odd one out. It had to happen, really, as seven was a prime number, but the mechanics were going to be awkward. Their game of Siege helped cement the trust between them, but it was going to take a lot more to trust people implicitly. There were still the visible groups of Jason's team, Percy's team, and her. Annabeth would have loved to say that she trusted Percy implicitly, as she once did, but the truth of the matter was that everything was too rushed to spare the time to properly catch up. Percy probably trusted her to that level (she hoped), but couldn't suddenly snap back to the person he was without dumping Hazel and Frank, which he would never do even if his fatal flaw wasn't personal loyalty.
"This is the Argo II's Supreme Commander Leo speaking. Now that we're all on board, I would like to cast off so that we can save the world as quickly as possible." Annabeth felt the corners of her mouth twitch, typical Leo, she really would have to apologise for all those times back at Camp Half-Blood when she threatened to neuter him when his humour overrode his preservation instincts and she was highly strung. Maybe after the quest she'd apologise to him... Not likely.
The ship picked up effortlessly, Percy was saving it the need of a crew. Watching the dark waters of the lagoon lap at the inlet, Annabeth was struck by a sense of peace. Turning from the shrinking glow of Camp Jupiter, she turned out to see the horizon. Absently running her hand across her forehead, she sent a prayer of thanks to her mother, for the Mark of Athena.
