Ariadne

Ariadne was a princess of Crete, daughter of the evil King Minos who helped the demigod hero Theseus navigate through the original Labyrinth in Ancient Greece.

History
Ariadne was the young daughter of King Minos, and she knew that he was evil, and that it was wrong to sacrifice people to the Minotaur.

Ariadne fell in love with Theseus the first time she saw him, and desperatly wanted him to live. She agreed to help him. Theseus was brave, kind, and handsome. He promised to marry her and take her with him back to Athens if he lived, and she gave him a sword and a ball of magic yarn.

After those attempts failed him, she used her ability to see through the Mist, to guide him through the maze safely, enabling him to kill the Minotaur.

Before King Minos could stop them, they all got back on their ship and sailed away, this time with Ariadne, Theseus' arm wrapped around her as they left Crete forever.

Aftermath
After they were out to sea, it is said Theseus grew bored of Ariadne. It isn't known why, or what caused this. Maybe he didn't like her at all, and resented her for making him take her away, even though he owed it to her, as she had thrown everything away to save him and his friends.

They stopped at the island of Naxos, and Theseus had an idea. He didn't want to have Ariadne for a wife, so he would simply 'dump' her, and go home to Athens without her, and he would never be bothered with her again. It must have seemed like a good plan, however cruel, because he carried it out.

So that night, when they were sleeping on Naxos, Theseus woke up the crew, and didn't wake Ariadne. He let her sleep, and they set sail without her, leaving behind the little girl that saved their lives.

Another account says that they let Ariadne sleep ashore because of her seasickness, and a storm drove them away from the island and broke their mast. They were then forced to go to Athens both to repair the mast and to reach home. In this version, Theseus forgot to change the masts because of his worry for Ariadne. Later, when he returned to the island, he could not find Ariadne.

In another version, Theseus left Araidne because she was awfully sick and he was going to go get medicine, but when he came back, she was gone. (Possibly because Dionysus married her)

Dionysus
Ariadne awoke, and she was alone. She looked around, and ran along the beach, calling for Theseus. She saw the sail on the horizon, and she knew that he had left her there. She collapsed on the ground, and sobbed. While she was on the ground, she cursed Theseus, and pleaded to the gods to make him forget to change the sails from black to white. They answered her plea, and Theseus' father Aegeus threw himself into the sea and drowned.

Dionysus was the guardian of the island of Naxos, and came upon Ariadne when she was still weeping. He comforted her, and was determined to make the poor girl happy again. Over time, he healed her broken heart, and they married.

With Dionysus, she was the mother of Euanthes, Oenopion, Staphulus, Thoas, Latramys, and Tauropolus. Her wedding diadem was set in the heavens as the constellation Corona.

She remained faithful to Dionysus, but later died, and her sons became kings of various cities and islands. They were fine without her, but Dionysus was not.

Dionysus then descended into Hades and brought her and his mother Semele back. They then joined the gods in Olympus, and Ariadne was made a goddess.

The series
Dionysus despises heroes because of what a 'hero' (aka Theseus) did to her. He later tells Ariadne's story to Percy Jackson, while keeping back from a quest in The Titan's Curse. Percy wants to save his friends, and then Dionysus decides to let Percy go on the journey he wanted, in hopes he'll get killed.

Ariadne then appears in The Titan's Curse, walking arm-in-arm with her husband. Percy notices she's a beautiful woman, and that this was the first time he had ever seen Dionysus happy.

Appearance
Ariadne is very beautiful. Beautiful enough to have snared Dionysus' heart, and beautiful enough to convince Theseus to take her with him.

Personality
Ariadne is a very kind person, and was willing to throw away everything she had for a total stranger. She loved him, but he was still a stranger. She was the daughter of a king, would presumably marry a king, was rich, was beautiful, and could have whatever she wanted. She threw it all away for a man.

Though Ariadne was a kind girl, when the man who she loved abandoned her, she cursed him for his faithlessness. It is unknown what made Theseus 'dump' her, or if it was just a misunderstanding.

Film
Ariadne has not yet been cast, and presumably will not be until the film version of The Titan's Curse starts production.
