The coliseum was silent - each group for their own reasons. The Beasts, despite having very strong representation, were the most confused. They did not understand a lot of the concepts that were being discussed, not because they were stupid, but because they focused their society on individual growth, and not the growth of the whole.
They formed and stayed in their own territories, and the only exchange they had with their neighbors was defending from expansion, or expanding themselves. This caused their growth as a civilization to stagnate, and their individual power levels weren't high enough to leave the planet, so their knowledge base existed only up to a certain point.
