Bianca Di Angelo is the forbidden daughter of Hades—but she doesn't know that yet. She has a brother called Nico Di Angelo and her mother Marie Di Angelo (Bianca is twelve and Nico is ten or nine). Bianca doesn't remember how her mother died. But while in the beginning of world world II, her mother dies by getting struck by Zeus after he tried to kill Bianca and Nico. Both siblings were brought to the lotus Casino after their memory was erased by the River Lethe and spent around 70 years there. After time skip passed, they were attended to a military boarding school all the way to Maine. While a dance at Westover hall, she and Nico were kidnapped by Dr. Thorn and finds out he was a Manticore. But luckily they were saved by Percy, Annabeth, Thalia, and Grover, the satyr. Also was helped with the hunters of Artemis. After the fighting ended, Annabeth was dragged away with Dr. Thorn. They were told that the Gods and monsters from Greek mythology were real. After they were settled down with the Hunters and Artemis protecting them—Bianca was invited to join the Hunters of Artemis. She had eventually pledged herself to Goddess Artemis and expect eternal Maidenhood, along with joining the Hunt. Later they had a ride with Apollo to Camp Half blood. While in capture the flag, Thalia and Percy were about to fight out of anger— but suddenly they all saw the mummy. The Mummy that held the Oracle and said— - "five shall go west to the Goddess in chains, One shall be lost in the land without rain. The bane of Olympus shows the trail, Campers and Hunters combined prevail, The Titan's curse must one withstand, And one shall perish by a parent's hand". And so the quest begun—Zoë Nightshade, the Lieutenant of Artemis convinced her to go with her. Along with Thalia and Grover—and Percy but he was following them with his Pegasus, Blackjack.

Mark of Athena timeline! this is where Annabeth begins her/their journey to find the statue of Athena Parthenos just like other children of Athena did in the past but failed. It takes just after she had broken her ankle while jumping out of the crumbling room of the Shrine of Mithras. (Personally in my opinion, she's a She/Them) Backstory: Annabeth was born from the brain of Athena, making her a 'brain child' of Athena just like her other half siblings. She was dropped off in front of her fathers house first thing when she was born. As she grew up in the household, her stepmother had a hatred to her for some reason. Always shushing harshly at her in the middle of the night when she cried loudly about spiders crawling into her bed. But they would always disappear when her stepmother appeared. She would try to prove by the bite marks but of course, they would always fade away quickly. One night she snapped and decided to run away with a hammer as weapon despite only being seven at the time. When monsters would appear, she would attack them with her large hammer as defense. Unexpectedly she met Thalia and Luke who were also runaways and became a family. They promised and was given a dagger by Luke, which became her combat weapon for the past years. When they were wandering around, they met Grover, who told them about Camp half blood and would keep them safe there. Especially Thalia, who was a daughter of Zeus. Everything was going as plan until Grover got nervous and lost track on where to go. By the time they found camp half blood, something found time. Thalia decided to stay to fight off the monsters as the others ran to Camp. Eventually Thalia was drained and exhausted and about to get killed until Zeus came up and turned her into a pine tree. Which now protects the barrier of Camp half blood. (But anyways later in the years Thalia comes back to life by the golden fleece after Luke betrays the Camp and becomes a hunter bah bah. Oh yeah and Luke dies)

Nico Di Angelo is the son of Hades and half sibling of Hazel Levesque, who is the daughter of Pluto, Roman version of Hades. He was born in the 30's but time passed by when his sister and him went in the Lotus Casino after his mother died so his memory would be erased. Besides his sister Hazel, his sister, Bianca sacrificed herself while in a quest with Percy, Grover, Thalia, and Zoë. But after the Roman and Greek fight, Will Solace, a son of Apollo began to start dating Nico :)

Hazel Levesque is the Roman daughter of Pluto and half sister of Nico Di Angelo who is the son of Hades. She was born in 1928 with her mother, Marie Levesque wishing all the riches of the earth from Pluto, even though the warning of the greediest wishes would bring the greatest sorrows. Marie still insisted because she was tired of being poor. Those wishes gave Hazel a curse, all the gems she would summon brings bad luck to people who touched it. And sadly her mother, Marie, used to use Hazel's powers for selfish reasons. After some years later when she joined school with mostly African kids but got bullied and got her lunch taken away. She still would refuse because the gems gave bad luck to people expect Sammy, who never did bully her like others did. But unfortunately with a fight of Pluto, her father and her mother— they moved to Alaska for six months and her mother worked as a servant for railroad workers, naval Soilders, and fishermen. She would always come home at night while smelling like fish and suddenly get possessed by a voice for terrible plans. Hazel and her mother were ordered to work in a cavern of an Island. She would work herself into tears and begging Gaea to stop but still had to work. Around 1924 in the carven, Hazel sacrificed to stop the awakening Giant and to save her mother. Hazel woke up in the Underworld and found out she was dead, she was sent to the fields of Elysium but Hazel argued that it wasn't fair. So her mom and Hazel went to Fields of Asphodel instead. Around Seventy years passed by and Nico Di Angelo, a son of Hades realized she was a child of Pluto and brought her back to the world of living. Which was possible because the Doors of Death were opened. Later when she was brought to Camp Jupiter, she met Roman demigods like Jason Grace, and Frank Ahang.

Earlier after he had just got claimed by his father, he had just found out about his rare ability of fire powers unlike any other of his half siblings.

Leo is best friends with Piper McLean, Daughter of Aphrodite, and Jason Grace, Son of Jupiter.

Thalia Grace is the eldest daughter of Zeus, along with her younger brother Jason Grace who calls Zeus—Jupiter in Roman. She was talked about being the pine tree years ago when Camp half blood just came around, Thalia, Luke and Annabeth had found Grover who told them about the Camp. So Grover traveled with the group, but unfortunately he was nervous about messing up and they got lost. When they finally saw the entrance of Camp half blood while being chased by monsters, Thalia decided to take the risk and hold back the enemies. She was exhausted and badly injured by the amount of the monsters fighting. In the last moment Zeus saved her by transforming her into a Pine tree who guards the barrier of the entry to Camp. She was only twelve at that time, Luke was fourteen and Annabeth was seven. over the time Luke poisoned the Pine tree and Annabeth, Tyson and Percy went for a quest to receive the Golden fleece and healed Thalia with it. But unexpectedly it brought her back to life as if nothing ever happened to her. Meanwhile the Pine tree Thalia used to be was still here as a barrier and the Golden fleece wearing it around was safe and sound. During Titan's curse Thalia, Percy, Bianca and Zoë went on a quest to save Annabeth and Lady Artemis. Bianca was gone after and Zoë too after fighting Luke and Atlas (Luke betrayed Camp and joined with Kronos to defeat Olympus) but they were able to save both Annabeth and Artemis. In the end Thalia had been offered to become a hunter of Lady Artemis and she unexpectedly agreed and is now the Lieutenant of the hunters after she took over Zoë.
