Leo was dreaming. Of course, this was normal if you were a Demigod. But Demigod dreams usually don't have floating yellow triangles in them. But this guy couldn't be that harmful. All he wanted was a puppet. Leo could afford a puppet... right? Rated T for reasons. THIS IS NOT LEO/BILL! I REAPEAT: NOT LEO/BILL! It's just a play on words guys. I own nothing but this story.

BRING ON THE FLAMES; I REGRET NOTHING!...also; feel free to adopt this...

This is... book 5! Omg! Now, for this I've decided to just make this story a bunch of funny stories that happen to the story, don't worry, there's still going to be a main story going on! So we have a plot! ;P

Who knew a late night walk could lead to more secrets? AU. CONTAINS SLASH CRACK PAIRING!

To be written. Not a summarizer. Rated T cuz' I use violence a tiny bit... more specifically I will be mentioning and even showing a small portion of it. (AKA Paranoia) Also not adding these characters until later because I'm lazy and it takes a bit of time to find all of them. Can't find a good shipping(But pincest is not in) Also yet to figure out a good genre set. Please review!
