Son of Tartarus

I take the shortcut to the Underworld

"What are you doing here? You should be helping me from the Underworld!" Zeus yelled.
Now, having a god mad at you, is bad. Having a major god mad at you, is terrible. Having a major god, with a lightning in his hand is even worse. Having the King of major gods , with his master-bolt in his hand, is the worst. And then there is having Zeus mad at you. His expression was pure anger, his electric blue eyes were warning, and his aura was hot.
His aura, not just hot, but it was so immense, it was almost visible. It smelled liked rain near him, but the most noticeable thing was not his aura, but his master-bolt aimed directly at me.
  After saying that, he repaired on my friends.
"A Demeter kid, a Dionysus kid, a Hermes kid and a satyr? That is what you chose? Are they going to help me? Seriously?" Zeus asked.
-"Hey!" All of them said in unison
-"Do not get me wrong, but non of those gods are specially powerful. This is a hard quest. That is why I chose the only son of Tartarus in millennia. He is powerful" Zeus answered, in a passive aggressive tone.
  After hearing this, I realised I had already pulled Zeus too far, and that if I wanted to get to the Underworld I should ask him as soon as possible.
"Almighty Zeus, we have a problem. We do not know how to get to the Underworld and we came here hoping to find .... a way to go" I said after I had realised it would have been a terrible idea telling him that we had planned to ask Hermes.
  Zeus sighed.
"The way to the Underworld is miles away, in California, if you haven't left already it is not very likely you'll get there in time" Zeus said
-"In time?" I asked
-"Yes. As you may recall, I told you that I was doing this at the same time that Hera is busy on a quest. This quest ends August 1st and if Hera comes back all this mission is doomed, and she will kill all of you for helping" Zeus answered
-"What? Why didn't you tell us?" I asked
-"Because you wouldn't have helped" Zeus answered as if it were obvious.
-"Yes! Of course I would have said no. You shouldn't be mani-" I started.
-"DO NOT TELL ME WHAT TO DO. I AM KING OF THE GODS AND I DO HOW I PLEASE, NOW GO TO THE UNDERWORLD AND HELP ME OR YOU DIE!" Zeus yelled. His voice boomed all over Olympus, maybe even people in the streets of NY had heard it. He had such a powerful voice, it sounded as loud as I thought it was inhuman to be, but then again he is not human.
  I looked over my shoulders at my friends who were all as petrified as I was. Finally, it was Harry who had the nerve to talk back.
"Yes, master Zeus. We will leave now"
-"You better!" Zeus growled.
  We all started to go when Zeus started yelling. We looked back and saw him on his knees trying to fight himself. He screamed, and then suddenly a different man, a blond younger man, with purple robes stood on his place. Even his master-bolt looked different, instead of being a celestial bronze weapon now it was gold. The only way to tell he was Zeus was because his eyes looked the same, he still had electric blue eyes.
"Umm... are you okay?" Tina asked
-"What? No! I've been fighting with my Greek counterpart, Zeus, for so long. Finally I belated him" The man said
-"Wait, are you... Jupiter?" Jay asked
-"Of course I am Jupiter, you little kid of Ceres" Jupiter confirmed
Wow I thought
"Now, what was I in?" Jupiter wandered
Suddenly, I got an idea.
"You were about to give us a safe transport to the Underworld" I answered
-"Why on earth would I do that?" Jupiter asked
-"Because, er.. We are your heroes" I said
-"I do NOT need some heroes to help me!" Jupiter growled
-"But we are saving you from Juno" Tina said quickly
-"How so?" Jupiter asked
-"Well, we are convincing her to, er... stay away from Olympus more" Tina improvised
-"If I wanted to do that, I would do so myself!" Jupiter snarled
-"Oh really? In your actual state?" Jay asked
-"What do you mean by that? TELL ME!" Jupiter yelled
-"With your Zeus form popping in all the time" I said
-"How dare you even..." Jupiter started. Then, as if by magic he started roaring in pain, and if you saw him carefully you could see his image flicker, and Zeus' too.  At the end, Jupiter won.
"Ok, so you might have a point" Jupiter said
-"See? We are helping you!" I told him
-"Well then, Follow me"
  Following Zeus, sorry, Jupiter, was not an easy task. He started flying and we had to run really fast to simply see him. Harry though was so fast that he could run normal speed and have to wait for Jupiter to get to him.
  Ten minutes later, I was tired already of the running, but we arrived at a mansion.
  The place was quite nice. It was like a modern mansion with most of the walls being windows, although they were also like mirrors cause you could see yourself reflected. It had some modern wooden steps up to some Greek styled columns made of metal. The door was made of wood and glass, and as big as a palace's door. On top of the door was a very well known symbol, a caduceus with two snakes on it.
"The mansion of Herm, er... Mercury" Tina offered
-"Yes. I am sure he won't mind" Jupiter said
-"Wait, we are going to break in? Fun!" Harry said
-"We, are not, you are" Jupiter said while pointing at Harry.
-"Really? Cool!" Harry said
-"Yes, and listen carefully, you need to bring here a backpack that is made of gold, it should be inside." Jupiter told Harry
-"Ok" Harry said
-"Oh, and don't forget, you must do it at maximum speed, do not let the cameras catch you"
-"No problem" Harry said
And with that, he ran into the house.

...

After almost two minutes, he was back.
"Taa Daa!" He said while holding the backpack
-"This, is the bag of Hermes. Anything you want, can be inside that bag, but for each thing you take from it, it will steal it from someone else, there are rules though. You can't get anything too powerful, or take it from someone too powerful" Jupiter explained
-"Awesome!" Harry said while putting his hand on the bag.
-"Now listen, you must use it to grab the machine of Thanatos. You will eventually give it back, but with it, you can travel to the Underworld easily. Try" Jupiter told Harry
Harry did as Zeus ordered. He reached into the bag and took out a tablet, like an iPad.
-"Oops!" Harry said
-"Wait, that is it. The Machine of Thanatos. It has the ability to take you to the Underworld" Jupiter informed.
-Yeah, about that, I will need a password" I said while holding the iPad
-"What?" Jupiter asked
-"Yeah, just let me try something" I said
  I typed "Thanatos"
Wrong password
  Jay typed "Underworld"
Wrong password
Tina typed "Death"
It turned on.
Looking in it, Shaggy found an app called 'Underworld Traveler' and we opened it. We all held hands in a circle except for Jupiter and Tina clicked on a button which said: Start Journey. We did.
