The Void Race was facing a unique problem of their own. They had too many geniuses that were worthy of being sent, but in this trying time, they couldn't afford to put all their eggs in one basket.
If they were targeted for some reason and lost all of their geniuses, then it would be a loss that they couldn't swallow.
The fact that they had the highest chance to replace the Pluto wasn't lost on those in the world.
So, they made a hard decision.
Their geniuses were separated into three Tiers for them. There were their Supreme Geniuses, existences that only appeared once a generation and dominated all the others. Of these, they had three, each one of which had dominated a generation of their own and fell into the proper window for entry into the Idol Battlefield.
Beneath these were their Classic Geniuses. There weren't more than ten to a generation. And then their Elites, of which there would be no more than a thousand or so a generation.
