Can I get a little 팬 fiction help...?

I've been dying to write a PJO chaptered fanfic for ages but I can't 큰 덩어리, 한 조각 of anything! So, could 당신 guys give me a prompt, like a little nudge? It could be:
first lines
pictures
brief ideas
fill-in-the-blanks
whatifs
quest ideas
또는 anything else 당신 can think of!
I won't exactly use the entire idea, I'll just take inspiration from IT. I need an action/adventure fanfic prompt (no romance please) with no slash, AU/OC elements 또는 fanon references. Just a nice little idea, not above T.
Thanks, and you'll get credit when I start the story :)
Remember, it's a PROMPT, not a whole idea...maybe a small quote 또는 small synopsis 또는 anything but not a FULL IDEA.
당신 can include Gods and it'll take place after TLO just no made-up pairings (Thaluke, Thalico etc) 또는 whatever. Maybe a quest idea, who knows?
Thanks for your help and props will be given out to everyone who 답변 :)
