Ideas for you :D
Kinda Lengthy
As you can tell by this chapter title, this idea is gonma take a bit of explaining. So, Gaea has awoken and destroyed the human civilization, except for Camp Jupiter and Camp Half-Blood(she finds the demigod panic amusing). I think this would probably take place more in CJ, but CHB could be incorpoated nicely. Reyna has returned to camp, but has been stripped of her praetorship for travelling to the ancient lands. Octavion is the current and only praetor. He becomes corrupt because Gaea messes with his head(you decide how and what he does). He starts doing some crazy shit, and Reyna gets help from Percy and Annabeth, who moved to New Rome after the war. This is probs only half formed, and it could take many directions from here. You decide.
Also, something else, Jason before the Lost Hero. G'night.
DEMIGOD AND POKEMON!!!!! SOMEONE WRITE THAT WITH ME!!!!!
