We were falling down the waterfall while drops of water from the Styx river fell on us, I didn't care much but my friends were screaming in pain, I wasn't completely sure if they would survive this. After a while falling and screaming, I saw a green area at the bottom. When we got closer we realized it was a big pillow made of grass. We landed on it as softly as you can after falling such a distance and the moment we all got up it disappeared from under our feet and we landed on the black and hard ground. Then we saw a Hydra standing in front of us.

"Welcome to Tartarus, you better get yourself comfortable, since you'll be staying here for the rest of eternity" it said and disappeared.

We started walking towards what looked as an ancient building, as we got closer we saw it was surrounded by monsters and pools of some sort of bubbling liquid that Annabeth described as a very powerful acid. Luckily for Grover, she said it just as he was about to step into one of those pools and he had enough time to stop himself.

Annabeth offered to scout ahead, since she could become invisible. We all agreed and she started walking towards the building while we were hiding behind a rock.

When Annabeth got out of our sight we heard a man's voice from behind us "Hey! Look who came to visit!"

Then followed by a woman's voice "Be quiet! The monsters will hear us!"

Thalia's eyes suddenly opened "Artemis?"

The man said again "What about me? I don't deserve a surprised look and someone saying my name?"

Then we saw them, Artemis and Apollo were standing next to us when Artemis made a surprised look, pulled out her bow, aimed it at his face and said "Apollo?" Then she waited a few seconds while lowering her bow and said "Here, was that good enough for you?"

He looked insulted but nodded, then they both turned to us "What are you doing here?" Apollo asked.

"We were on our way to try and find my father, Hades and Zeus. We thought maybe they had an idea about how we can defeat Kronos" I said.

"Well... Getting into where their locked in is something I doubt you could do with so many monsters around" Said Artemis.

Just then Annabeth appeared in front of us "I couldn't get close enough to see, there were too many monsters. Oh, I see we have company" she said and pointed at Artemis and Apollo.

We all turned to look at them "I know of a way to get out of here, but it won't be easy" Artemis said.

Apollo looked at her and then at us and said "and you think that while their stuck here in Tatrarus they would care about how hard the way is?"

Artemis gave him a hostile look, we all agreed to come with them.

Artemis pointed at a crack in the wall and started walking there, we all followed her.
