Forgotten prophecy

The war against Gaia has concluded and the heroes of Olympus have been victorious. But now a new battle has emerged, one that is possibly just as dangerous. Greek and Roman demigods have begun to disappear, taken by some unknown new entity. The gods themselves do not know the identity of the culprit. With this in mind a new prophecy is made, one that has dire implications. Oc story.

Now for those of you debating whether to read this I want to state a few things for the record.

1. This is not my story. This is a story of a friend of mine who gave me permission to repost it.

2. It is very well written and Percy is in the story. He is not the main focus of the story.

3. Character death is possible.

4. This is beyond original in its plot and sub-plots through out.

I would recommend reading the first 5 chapters before you say no.
