An Undertale x Percy Jackson/HoO crossover fanfiction.
~-~-~-~
  What happens after your favorite monsters from underground reached the surface and climbed down Mount Ebott? Frisk couldn't resist having another adventure on the surface.
  After the war with Gaea ended, the Seven thought they could rest but instead the gods gave them a new quest. 
  Will this be a good thing to the world or will this be chaos?

Disclaimer :
• Percy Jackson/ Hoo belongs to Rick Riordan
• Undertale belongs to Toby Fox
I do not own anything else besides the plot.

Right now this seems to be the first Pjo/UT that isn't crap on the first chapter. Trust me. I scoured FF.N and AO3 it was hard finding anything here on Wattpad.
