Can I get a little অনুরাগী fiction help...?

I've been dying to write a PJO chaptered fanfic for ages but I can't বড় দলা of anything! So, could আপনি guys give me a prompt, like a little nudge? It could be:
first lines
pictures
brief ideas
fill-in-the-blanks
whatifs
quest ideas
অথবা anything else আপনি 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 অথবা 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 অথবা small synopsis অথবা anything but not a FULL IDEA.
আপনি can include Gods and it'll take place after TLO just no made-up pairings (Thaluke, Thalico etc) অথবা whatever. Maybe a quest idea, who knows?
Thanks for your help and শ্রদ্ধার্ঘ্য will be প্রদত্ত out to everyone who উত্তর :)
