Backstory and Alterations
-Camp Half-Blood and Camp Jupiter have spatial-bending doors that connect them to each, allow people to walk freely between camps
-Apollo's punishment was to be Jason's servant on his quest, then a Mortal butler to the Hunt for a year.
-Jason broke up with Piper over a prophecy pertaining to him.
-Piper was actually one week pregnant when Jason left. She wasn't ready to be a mother yet, so Artemis "freezes" the pregnancy, meaning that the baby's development was frozen in time, Piper doesn't feel any pregnancy effects, and anything that Piper does health-wise doesn't affect the baby until Piper feels she is ready.
-Jason actually died while sacrificing himself to kill all three Emperors before they could start the battles with the Camps. His prophecy is:
Since the world fell to Fire,
The Sky's journey is not done
As the three have risen as one
To prevent a world of endless strife
The Sky must give his life
-Apollo still fought the Python. He looks after Tristan just as much as does his kids, as he feels he could've saved Jason.
