Clint
"Suit up."
It was all that needed to be said. Everyone charged away, ready to do something, anything. They didn't even question Percy, which was less odd than it should have been. The kid just gave off an aura of quiet authority, and everyone around him just gravitated to his leadership. He gave them even fewer details than Fury ever did and they already trusted him more than they ever had the SHIELD director.
A few minutes later they were outside the cemetery Percy spent so much time in. He tossed a large gold coin into the pot before saying something in another language. It sounded a bit like Greek, but it wasn't quite right. The phrasing was older.
*"Η θεά μου δίνει τη μετάβαση στην κοιλάδα των Ηρώων."
Thor let out a soft gasp as he stepped through, looking with wonder at the plain cemetery. Clint glanced around at the rest of the Avengers; they all looked just as confused as he was.
"I have never been granted entry here before. Thank you young hero for allowing me such an honor." Percy nodded distractedly.
"Ok I think I have the prophecy mostly figured out. I wish Annabeth were here; she'd know. It's not even that complicated this time." Percy muttered. Tony raised his hand timidly.
"I don't know what you two god-like people are seeing but all I see is grass and headstones." Thor looked mystified for a moment before understanding crossed his features.
"The Mist conceals your vision. Let me-" Thor reached out when Percy smacked his hands away.
"No. You can't. Thor, we won't find it. It has to be them. They can't be clear sighted. Not yet. That's why I didn't invite them." Steve glared at the teenager.
"We need all the information. What are we supposed to be looking for? How can we find something, if we don't even know what it is?" Percy shook his head, running a hand through his already messy hair. He was the only one not suited up. He had even refused the bulletproof vest Natasha had tried to get him to wear. Instead, Percy was in his standard orange T-shirt and jeans, a ballpoint pen flipping through his fingers easily.
"I'm not sure. All I have is the prophecy, which goes like this; First came the sacrifice of warriors who once made this land their home, whom rest in the eternal peace of Elysian has yet to come, great tombs of heroes with polished marble hiding an earthen prison, only mortal eyes can find. That's the first of three parts. We're in the first part now that's the quest we're on, so we don't need to worry about the rest of it." Percy turned in a circle. Clint was confused.
How did any of that relate to a tiny cemetery on the Upper East side of Manhattan?
"Obviously the first line is about the Giant war, and those who died fighting in it. Then the second line has to be about Annabeth. She's the only soul unaccounted for. Nico checked. Twice. The third line is about this place! The Valley of Heroes. The last line is about mortals; only you guys can find her. Or the entrance. I don't know." The son of Poseidon kicked the iron gate in frustration. Thor shot everyone an I'll-explain-when-we're-not-around-a-grief-stricken-volatile-demigod-of-the-sea look. Clint nodded back, mildly impressed with the clarity of Thor's unspoken message.
"Then we'll spread out and start looking for an entrance. You said an earthen prison right? So we look for something that will lead us underground." Steve soothed. He waved everyone in different directions, and everyone moved out immediately.
