Second Titan War, Part Two

The Second Titan War, or the Second Titanomachy, was the conflict between the forces of @Olympus and the @Titan Army, which arose when the Titan Lord @Kronos attempted to take his revenge on the @Olympians for defeating him and sealing him in @Tartarus. He was opposed by the Olympians and the demigods of @Camp Half-Blood, including @Percy Jackson and the demigods of @Camp Jupiter, including @Jason Grace. It began on December 21, 2005 and ended on August 18, 2009.

The war revolved around Kronos' plans, who hoped to rise from Tartarus and rule the world once more by defeating the gods. There were five major battles over the course of the war; the Battle of the Labyrinth, the Attack on the Princess Andromeda, the Siege of Atlantis, and contemporaneous battles of Mount Othrys and Manhattan. It lasted approximately four years after @Luke Castellan stole the @Master Bolt and the @Helm of Darkness.

Part Four: The Battle of the Labyrinth

Due to his failure to kill the Ophiotaurus, Kronos kept true to his word, assigning Luke as his next host. However, before Kronos would take Luke's body, the latter would aid him in planning an invasion of @Camp Half-Blood using the @Labyrinth, which had an entrance hidden between two rocks which Percy and Annabeth found while playing a game at @Camp Half-Blood.

In order to pass @Antaeus' Arena of @Antaeus in the Labyrinth, Luke had to assign some of his monsters to fight to the death to please the giant. Then a captive Percy arrives along with @Annabeth Chase and @Rachel Elizabeth Dare. Percy dares Antaeus, also a son of @Poseidon, to fight him. If Percy wins, then him and his friends get released. If Antaeus wins, then they all die. Percy faces off against three opponents, the first is a Dracaena, then @Ethan Nakamura, who was defeated with some effort and the giant himself, who was defeated by Percy. As a result, Luke sent his monsters after them, but they escape with the help of @Daedalus' hellhound, @Mrs. O'Leary.

During this time, @Oceanus began to make war with Poseidon, incapacitating him when the other gods fought @Typhon until the final battles at Manhattan and San Francisco.

Part Five: The Last Olympian

When the time had come, Luke was somehow put into a trance. Two @Telekhines, along with Ethan Nakamura, perform a ritual to resurrect Kronos. Percy arrived to stop the ritual, but it is too late. When Ethan pledges allegiance to Kronos, the Titan Lord rose inside Luke's body and was given the reforged weapon, @Backbiter, his scythe with which he had used to kill his father Ouranos. However, Percy was rescued by his comrades, notably Rachel, who threw a blue plastic hair brush at Kronos, allowing Percy to get away. @Nico di Angelo sealed their survival by summoning a boulder over the fortress where the ritual was performed. This also saved Camp Half-Blood by preventing Kronos from taking part in the Battle of the Labyrinth. Unfortunately, Kronos now knows Nico's secret: he's a child of the @Underworld. After the battle, many minor gods decided to defect and join the Titan Army. This resulted with their children and all the unclaimed demigods to do the same as they feel enraged for not being claimed or not having a cabin representing their immortal parent at camp and would be forced to stay in @Hermes' Cabin (Cabin 11) for years.

Part Six: The Death of a Hero

During the Battle of Manhattan, Luke was completely controlled by Kronos. During this time, Percy learned that when Kronos achieved full power inside of Luke's body, he would burn through and attain his true immortal form, which would mean any mortal that was in the vicinity would be destroyed, and empower the other Titans, giving them ultimate power. To combat this, Percy also bathes in the @River Styx as part of Nico's plan.

Kronos made his way to the throne room of the gods with Ethan Nakamura, destroying the city of Olympus as he did so. Meanwhile, Percy, Annabeth, Grover, and Thalia followed closely after. @Thalia Grace's legs were trapped under falling debris, saving Annabeth from @Hera's curse and the others continued on. Kronos battled them in the throne room when they arrived, but Annabeth was able to catch Luke's attention, reawakening him, if only partially.

Percy convinced Ethan that total destruction was not what his mother, @Nemesis, the goddess of revenge would have stood for. Ethan betrayed Kronos and attacked him, unsuccessfully of course, as his sword shattered against Luke's invulnerable body. Several shards lashed back at Ethan and impaled him, and he staggered to the ground. Kronos, now having an internal struggle with Luke, opened a fissure in the floor beneath Ethan, and he tumbled to his end. Kronos continued to batter the trio, getting closer to his ultimate transformation to his original self.

But Annabeth managed to coax Luke back to his own mind. Luke let Percy knock Backbiter into the hearth, where it was destroyed by the goddess @Hestia, leaving Luke defenseless. A beaten Annabeth gave Percy her knife, as they both realized that Luke was the true hero of the prophecy. Percy gave the knife to Luke, who stabbed himself in his mortal point, his left shoulder.

Around this same time, Roman Praetor Jason Grace, son of Jupiter, led Camp Jupiter to attack @Mount Othrys. As the Romans fought @Scythian Dracanae, Jason toppled the black throne of Saturn and destroyed the Titan Krios singlehandedly. This possibly aided Luke in gaining control over his body and helped Camp Half-Blood defeat the Titans in @Manhattan.

After the battle, Percy, Annabeth, and @Grover Underwood looked away from the following explosion and Kronos's fading screams. Luke was left lying on the floor, dying. Annabeth said that he would go to @Elysium and Luke replied, "Think … rebirth. Try for three times. Isles of the Blest." Annabeth replied that he always pushed himself too hard. Then Luke asked Annabeth if she loved him, and Annabeth replied that she thought she did but truly thought of him as a brother. Then Luke pleaded to Percy to not let this happen again. With that Luke died just before the gods arrived, after defeating Typhon, thanks to @Poseidon returning. In the end he was taken away by the @Sisters of Fate, after being blessed by @Hermes, and remembered and honored as a hero by not only Percy, Annabeth, and Grover, but by all.

Aftermath

Percy Jackson was given the gift of becoming a god, but declined due to his love for his friends and Annabeth Chase, who he was finally able to admit his feelings to. Instead, he requested that the gods claim their children by the age of thirteen and for Camp Half-Blood to construct cabins for the minor gods and Hades, and that the peaceful Titans should be released. He was thinking of @Calypso in particular, a kind, beautiful Titan that was confined because of her father @Atlas, but all the other peaceful Titans were also released.
Grover was promoted to become a member of the Council of Cloven Elders by @Dionysus, and was deemed a Lord of the Wild. From this, he gained the respect of many nature spirits and the satyrs. He also was coordinating demigod searches with more demigod children being claimed all over the world thanks to Percy's request to the gods.
@Tyson was made a General of the Cyclopes for his bravery in leading the charge against Typhon. He was also had the choice of any weapon he wanted which was a new club to replace the one that was broken in the battle. Zeus said that they would search for the finest club that could be found. (Tyson refers to his club as a stick.)
Annabeth, as a reward from her mother @Athena, was given the opportunity to rebuild Olympus in whatever way she wants as its new architect. @Ares, @Aphrodite, and @Apollo almost immediately asked for numerous statues of themselves everywhere. She was also in charge of the designs for the new cabins at camp.
Rachel Dare went to Camp Half-Blood and takes in the spirit of the Oracle now that the curse had been lifted as Hades' children have their own cabin and are accepted by the other gods. She immediately revealed the next Great Prophecy, which the Romans had already remembered as the Prophecy of Seven. This will be fulfilled during the Second Giant War.
After his success at the Battle of Mount Othrys, Jason Grace was raised on a shield by the entire Twelfth Legion and promoted to the rank of praetor. He served as praetor for only two months before he and Percy were exchanged in preparation for the upcoming war with the Gigantes.
Following the conclusion of the Second Titan War, the protogenos of the earth, @Gaea, stirs from her slumber and begins preparing to raise the @Giant Army for the Second Giant War.
