They met in secret.
Five very special people whose parentage made outcasts of them all - even before they had been given any opportunity to prove or disprove their worth to society. Indeed, had they been discovered at birth, they would very likely have been killed.
So they started by owing humanity nothing.
Nothing except the bitter hatred and resentment of any outcast in any time.
But with a difference.
For these were starbred. These combined, if not the best, then certainly the strongest attributes of man and Centuarian. These five were infinitely superior to man - and they hated as superior beings might. Not with a desire to destroy, but with the need to control - absolutely.
And so they met in secret.
