Percy turned to Annabeth and Caleb, "are you sure you guys want to do this?""Yes!" They yelled, "we told you, the only way to get the oracles staff is from this wyvern" said caleb. The three demigods were on a mission to find the oracles staff, a staff that was rumored to give the holder knowledge of the next two hours, it only worked once a week though, unfortunately the staffs location was in a wyverns cavern deep in mt. Diablo. The adventurers all took a deep breath and walked into the cave. About a mile in a deep voice droned, "sssso what would thessssse three young people be here for? Hmmmmm?", Percy pulled out Riptide and pointed it into the shadows in the cave, "we just want the oracle staff" he said, "well then" droned on the voice, "you'll have to go through ME!"he yelled, something struck out of the shadows heading strait for them. Caleb muttered a word and a shimmering wall stopped the wyvern in its tracks, "Ahhhh" the wyvern said again, "a ssssson of Hecate!", Percy tapped Annabeth and Caleb and pointed at the wyverns claws, clutched tightly in them was a gold staff with a baseball sized pearl on the end of it. The wyvern was bashing the magical wall and Calebs concentration was failing, with a final roar the wyvern hit the wall and it shattered knocking Caleb unconscious in the process. The wyvern slithered forward and swallowed Caleb whole, without hesitation Percy ran forward and dove strait down the wyverns waiting mouth, Annabeth choked down a sob and threw her dagger at the snakelike figure, he just laughed "your puny knife can do nothing to my ssssscalessss!" The wyverns eyes suddenly widened and then closed, as his head fell heavily to the cave floor. A sword poked out from the dragons belly as Percy cut himself out, he dragged caleb out with him and fell heavily to the floor. "Percy!" Annabeth cried, she ran over and hugged him. Percy pulled himself up and grabbed the oracle staff, "well" he said, "lets get back, we need to get him to the infirmary, he overtaxed himself" Percy motioned to Caleb who looked very pale and covered in wyvern guts. They started heading back up the cave.
