War of the Olympian Demigods
The Olympian Gods of Greece are real... and because of them the human world is about to fall into chaos. The lust of Gods and Goddesses is as great as any humans, or perhaps even more. They have mated with many humans over the centuries and have sired many children as a result. These children, known as demigods, often grow to become people of great importance in the human world, guided by the unseen hands of their divine parent, for they, though powerfull and immortal, are not able to interact with their children. It is forbidden since time immemorial, as is tempering with the free will of the mortal humans.
But one day everything changed. The son of Zeus, Heracles (Hercules in Latin), rebels against the Olympian Gods, enraged by the loss of his wife and children, who he slew while under the effects of a strange magic spell. Suspecting the Gods, he starts to rally all the demigods to form an army to fight against the Gods themselves. If any approached demigod refuses, they are cut down where they stand. However, the demigods alone are not enough to successfully invade the realm of Olympus. However, one day word of the mythical titans, archenemies of the Gods, reaches Heracles' ears, and he decides to set out and find them, to free them from their prison and make them his allies
or slaves, depending on how cooperative they are.
The Gods, unable to interact with their children directly, send out all sorts of mythical creatures and monsters at their disposal in an effort to stop them. They all fail miserably, posing little challenge to the ever growing demigod army. In a last ditch effort, the immortals attempt to fight fire with fire. They send out servants to bring together the few remaining demigods who had not yet been found and recruited into Heracles' legion. Among those few are the young Palici twins, Alec and Heros, sons of Hephaestus, the blacksmith of the gods. They are seen as the weakest among the group, and are treated as such by most of the others, because neither of the twins is able to controll fire or magically forge mighty blades like their father, only ever being able to produce a crude, subpar weapon at best.
One day Alec disappears, leaving Heros to set out on a quest to find his missing sibling. The leader of their small band of demigods, another son of Zeus named Carnus, attempts to persuade the younger demigod from leaving on this quest, but ultimately falters to the persistence the son of Hephaestus displays, though also suspects something greater at work behind the disappearance of the other twin. Knowing Heros was too weak to fend for himself against any agents of Heracles that might cross his path, he assigns him a bodyguard. She (your character) is one of the most powerful members of their small organization.
As the subsection suggests, this will take place in modern times. Taking a page out of the book of series such as Percy Jackson, the Greek gods are real, though they and the nature of their offspring remains hidden from most of mankind. This war is one fought in the shadows of modern society, but also one that threatens its existence, as Heracles' hatred for the gods blinds him to what the unleashing of the titans might to the world itself.
The relationship between our characters could be rocky at the start, with her being a powerful demigod already, while he starts of weak. However, as the journey progresses she will come to see his true strength, his determination to stand against any odds, and his slow growth into something more epic than she could have imagined him to be at first. Together they will uncover a conspiracy bigger than any of them.
