Maeonian Drakon

The Maeonian drakon, also known as Draco Maeonius, was a drakon, originally of Lydia, that attacked the village of Maeonia (in modern-day Turkey). After it killed his friend, the giant Damasen slew the monsters. Because of this, his mother Gaea imprisoned him inside the depths of his father's realm, Tartarus.

History
Around the time of the first Gigantomachy, the Maeonian drakon attacked the village of Maeonia (in modern-day Turkey). The naiad Moria's brother Tylus accidentally touched a serpent, which then attacked Tylus, coiled round his body and suffocated him; Tylus was not his first victim. Moria only could helplessly watch her brother die, but then Damasen, a Giant son of Gaea, arrived on the spot; Moria implored him to help and he killed the serpent, hitting it with the trunk of a tree he tore out of the ground. Then a female serpent, the slain monster's mate, appeared and used a magical herb, referred to as "Zeus's flower", to bring the dead serpent back to life. Moria then used the same herb to revive her brother.

Damasen's killing of the drakon was an act his parents could never forgive. Gaea opened up the Earth and imprisoned him inside his father's realm, Tartarus. The Protogenoi allowed him to continue farming, but he was never allowed to see the sun or the stars again; it was their way of showing him how meaningless his life was. While in Tartarus, he was given the endless task of slaying the Maeonian drakon.

The House of Hades
After Percy Jackson sustained injuries too much for his healing abilities, the Titan Iapetus led him and Annabeth Chase to the area where Damasen was kept. There, the Maeonian drakon attacked. Annabeth asked if there was any way they could stop the creature. Iapetus replied that they couldn't. Annabeth then told Iapetus to get Percy to safety, while she distracted. Iapetus said there was no need, and just as he said it, Damasen arrived and destroyed the monster, complaining that there weren't enough bones.

Later, Damasen rode the drakon into battle against his father, Tartarus.

Appearance
According to Annabeth, the drakon was actually a beautiful creature. Its hide was green and yellow, like "sunlight through a forest canopy," and its eyes were the same shade of sea green as Percy's. Annabeth described it as easily as long as a subway train. She described it as a regal and amazing monster.
