Trials for the Gods

Greek gods? Just myths, right?
My name is Iris Dimitriadis, daughter of Zeus, the supreme ruler of the gods.
A few years ago, my whole life changed the moment I received a prophecy.
If you've stayed up to date with my life, you'll know I was one of the prophesied demigods that helped save Mount Olympus from destruction.
The world has changed significantly since then...The barrier between the gods and mortals was demolished the moment the gods came to reveal themselves to the mortals of Earth.
Zeus has decided to further showcase their might and power. To prove they are the 'Rulers of Humanity and only true gods', an event was established, where demigods must compete annually via a set of perilous Trials.
The Trials take place yearly after the cold season has ended, on an island named H N - Hirakleia Nissos.
Meaning the Island of Hercules.
As demigods we are now solely trained to survive these Trials.
Thus, creating a modern form of entertainment for the gods.
The offspring of Zeus, Hades, Poseidon, and Apollo are in a deadly predicament once again.
