The Demigod Line

Prologue
Once when the fist humans came to Earth before the gods, the protogenoi had mortal affairs. Their children became the first demigods. Then the demigods married each other, aware of their ancestry and retaining their protogenoi parents' powers. Kronos then castrated Uranus and the Titans had children with the demigods. Those demigods married each other and had children. Then, when the gods took over from the Titans, the gods had affairs with some of the Titan demigods. And so began the line of unique demigods that had powers of the Greek gods; some had powers of Hades, some had powers of Kronos, and some had powers of Nyx. The family became so big some had to move away and became so distantly related they could marry each other. Now, in the current generation, two twins, Corum and Aly Liam became the most powerful demigods to exist in millenia, inheriting powers and traits of every protogenoi, Titan, and Olympian, making them powerful enough to rival the gods and even Gaia herself.
