The Prophecy of Eight

Eight demigods shall answer the call.
To storm or fire, the world must fall.
A Gunslinger brought unto the fray,
One ancient evil at which he must slay.
The world unknown, brought into reality,
With unending lives facing mortality.
An oath to keep with a final breath,
And foes bear arms to the Doors of Death.

The story follows the heroes of Olympus story, but it will not unfold the same way, with a new character and new conflicts being brought into the forefront.

After all, the original way Gaea went about it doesn't seem the smartest in retrospect, right?
