Chaos (The Ultimate Crossover)

Secrets

As a hunter, you never know what will happen. It could be anything. But this was just creepy. A guy in a trench coat was knocking on our door in the middle of the night. At first, I thought it was Cas. He always forgot his key. Then I realised that I let in a stranger. He was blond and was talking in a britush accent. When he didn't noticed I grabbed my gun but it wasn't there.
"Looking for this" he said with my gun in his hand.
"Who are you?" I said.
"John Constantine. Exorcist, demonologist, expert of the dark arts. And you are Dean Winchester."
"How do you know my name. And Constantine. As in the superhero?"
"Don't get mistaken. I am not a superhero. I help them yes but I don't save kitties from tree tops. No. I defeat demons and ghosts."
"That can't be. You're fiction."
"I am deeply offended. You are a man of letters, correct?"
"Legacy but go on."
"Haven't you rummaged through your bunker? If you have, you will see that comic book writers were in fact men of letters. Have you seen the door with 10 locks?"
"Yeah?"
"Well that's a portal to my universe. You could say we are a mirror of each other. I came to warn you that Olympus has fallen."
"Yeah, we know"
"Okay well, I need to open that door. With the ten locks." Just then Sam came running down the stairs and fell face first.
"Sammy!" I went running to the stairs to help him.
"I'm all right. I had a dream of a prophecy."
"Again?"
"Yeah. This was different though. I saw an omega, a rune of some sorts, a nordic rune, a hieroglyph and a helmet. A golden helmet like the one Doctor Fate uses in the comics. Then a tall man spoke in a strage voice.
"He said:
'The Darkness will be light.
The Pit will rise
Chaos will reign
Olympus will fall
The Heroes behind Shadows will come,
The Hunters will aid,
The Children of Hecate will betray her,
The Heroes of Olympus shall Rise to Power.
The heroes of the mirror will come to restore order'"
"Hello there! Hi, my name is John Constantine" Constantine said.
"Shut Up" Sam and I said in unison.
"Wait. The John Constantine. But you are a comic book character. Who are you really?"
"Ugh. Again? Your moronic brother asked me the same question. Comic book writers are legacies. Men of letters legacies. In my world, a bunker just like this one exists. Have you ever seen the door that has 10 locks in the basement?"
"How do you--"
"I know. Now do you know someone named John Winchester?"
"Yeah. He was our father." I said remembering dad's death.
"Well I knew the guy. He hid 10 keys all around the bunker. Let's go find them"

10 minutes later we found the first key. It came with a letter.
Dear Sam and Dean.
I have to go. It's not a hunt. It's far worse. Aphrodite has requested my help. We have been friends since the passing of your mother. She's having a baby. A girl. But it is bad because the baby is Ares'. Bad things will start happenning. Dean take good care of Sammy.
Love,
John Winchester

After that we kept stumbling on letters to us. Some were about The Greek Gods, Nordic, Egyptian, etc.. Then we found the last key. The letter wasn't a letter. It was a bunch of words in greek or something. A spell.
"What does this mean nerd" I called to Sam. I handed him the paper. He began to read but it was no use.
"Don't know."
"Gimme that, you pile of bullocks. It says here:
'Chronon spell.
Time is at escence
to change or uncover the past
One will venture back at last
To find what was forgotten
You will need ingridients ten
One blood of unicorn
One piece of the past
One drop of ichor
Three shards of celestial bronze
One shard of stygian iron
Three shards of cursed rubies.
"It's a spell. It will come in handy. Now let's go open that bloody door" he said aproaching the basement. It was very dark and I tried turning on the light. No response. The door had an eerie glow. Like gold.
"Well, well. If it isn't the Winchesters. And of course John Constantine. The exorcist." said a voice in the door frame. I reached for my gun and Isaw Sam do the same. We aimed and shot. Nothing.
"You thought that bullets could hurt me? I'm what your Nightmares are made of."
"Oh please. It's getting a bit old, don't you think?" Constantine said and flung a flask with green liquid. It broke and burned the shadow.
"What was that?"I said.
"Greek fire. Comes in handy. Now open the door"
Fuve minutes later, the door was opened. Without another word, we crossed the portal.
