This was wrong but the fates have spoken Zeus said descend into hell they fell I turned to Poseidon he said be careful brother one wrong move and you face a war one which you have never seen. I said and I will join him Hades stood up and said so will I. Hera said he is king you owe him your fealty. I said we are loyal but you have wrong us greatly he thinks he can get away with whatever he wants since he is king but we are giving him notice that he better get his act together or else. We left and arrived in Atlantis Poseidon said I hope our children make it Hades said Zeus won't let them go on with their lives he will imprison them on Olympus. I said what do you mean he said time down there is different 6000 years will equal to 600000 years for them they will have changed. I said Chaos save us Poseidon said I don't that will stop them then Poseidon said I am sorry for the wrongs I have committed against you I said I am also sorry I was being stubborn. Then Hades said when you two work together great things happen like Athens a power house in its own right during its time. Then there is our latest creation that we indirectly made I smiled and said they will make it the odds may be against them but when has that mattered.

After your escape Tartarus disappeared monsters are banding together and trying gain power to control Tartarus then they will attack the world above destroying everything in their path Annabeth said we do you want us to do they said take over Tartarus. We looked at each other then Annabeth said ok we will do it they said it will be tough but you will make it and you will get to see the sun again. I said we need to gather an army Annabeth said the Brass Keep we can find what we need there we head to the river of Phlegethon we headed out and found what we were looking for and headed up river.

We arrived at a huge fortress then some I saw ballista trained on and some scorpions. Then 200 monsters charged out I turned to our guide and said go an hide on that hill pointing behinds us.

We ran into Hyperion he said my favorite demigods Percy didn't even responded and created a pillar of earth that shot him through the celling and he went flying then I used my sense and found 2 anomalies. Percy and I went and found an odd sight Zoe and Luke locked in the same cell cuddling trying to keep warm. Percy went in and woke them up we all left we gave them some weapon I gave Zoe my bow and arrows Percy gave Luke his spare sword we found our guide he was hiding right where Percy told him to. We walked for about an hour and found a cave and setup camp. We asked our guide whose name is Duke we asked him to keep watch he said he would gladly Percy gave him a dagger we activated our tent and asked Zoe and Luke to join us in the tent. When we got in Percy asked what happen Luke went first he said Zeus snuck into the Underworld and threw me into the Pit when I was in Elysium. Then Zoe said after the he got done with you guys after I died he came and said I could either have sex with him or be thrown into the pit I kicked him in the nuts he struck me with his Master Bolt I was hunting monster around a swamp for a while this was Peres territory he caught me and handed me over to Hyperion and he threw me in a cell and 6 months later he threw Luke in as well saying he wanted to keep his demigods prisoner together. The Luke said we kinda of bonded over the years I said do you want to return to the surface Zoe and Luke said no Zeus won't allow us. Then Percy said do you want join us Zoe said sure then I explained our plan. Luke said if you want to protect the upper area I know of a place it is a village it is an 8 month journey there I said lets go then.
