Doomed

One child shall rise,

strongest of all.

A third one will die,

forgotten since Fall.

Seven will unite they're powers as one,

because the End of Days have begun.

Now, in the midst of the 1st Major Olympian Civil War, one demigod will stand-up to face his fate, leaving seven others to follow. And one will die. Who will be the demigod? Who will be the seven to unite they're powers as one? Who will die forgotten? You must submit your answers
