Percy Jackson Writing Resources

Okay guys, so there's been something bugging me lately about the fanfictions I've seen for PJO: the lack of mythological diversity.
Most importantly: there are more than twelve gods out there; don not, I repeat, DO NOT think that if you want a powerful character xe has to be a child of The Big Three. (In fact there shouldn't be any children of the Big Three, AT ALL). Try for some more parental diversity. 
Secondly, there are more monsters our there besides the Hydra and hellhounds, trust me.
So in order to help all of you get a bit more creative with your mythology I have found the three best resources for you: 

Zeus isn't the only god with a magical item to be stolen. Here's a list of magical items in mythology:  en.wikipedia.org/wiki/List_of_…

Need to find a unique parent for your demi-god? Need a divine villain? This is a list of all Greek immortals:

Every demi-god gets attacked by a monster something in their life, but not all of them get attacked by the same monster. Here's a list of every Greek creature:

And if you have any questions as to how to incorporate these factors into your story, just message me. I have quite a bit of experience and probably will be able to help. 

Go! Rejoice in your new-found diversity resources! I hope I helped and didn't sound too cynical!
