These words weren't as crazy as what they expected, but the more they thought about the implications, the heavier they felt.
The Void Palace was the symbol of humanity. Sending their descendants was more than about training. If it was just this, they would be able to train their own descendants far better. After all, they had the deepest understanding of their Lineage Factor and how their bodies worked, figuring out a training plan for just a single kind of person was far easier.
No, sending their disciples was in one part to remind the Human Domain of the kind of potential the Morales had, making their prestige greater and making it so that it was even less likely that others would have designs on them. But, more importantly than that, it was to forge a united front.
The humans had an obvious weakness… they followed too many paths as a Race. It was easy for them to butt head and to push and pull in all sorts of different directions. The Void Palace was needed.
