The Déf̱tero Próso̱po Group

'''SPOILERS! DO NOT READ IF YOU WANT TO BE SPOILED! IF YOU WANT TO BE RUINED, READ THEN! RUIN YOURSELF!'''

The Déf̱tero Próso̱po Group, or The Second Person Group, is a group of people who were created by the Titans for use of war.

History
In the Second Olympian War, the Titans took demigods who were still to young to fight and did not know their true identity, and created a second person out of them. The same person, but older, more beautiful and mature, and stronger, one who would stay on the Titans side. The names were changed, obviously, and they were unclaimed.

The demigod who was used by the Titans would be put in a deep sleep, while the people that knew them would be shrowded by Mist.

Sometimes though, it would go wrong, and the person would show up at Camp Half-blood, and fight for the gods.

If the Second Person died, then the Titans would either kill (if they were weak, on the God's side, etc.) the First. If they were strong, then they would send the demigod back to his/her normal life.

When the Titans were defeated, one of the last Titans killed the Second People and put the First back into their normal life, and they remembered nothing. The Titan made a secret chest and put pictures, information, and other things having to do with Second People an hid it, hoping he/she could use it if another War ever came.
