Here is the first question I wish to put up for discussion:

Kishi has established that Hagoromo chose Asura as his successor... and Indra, outraged at this decision, fought with his younger brother.

In terms of timeline establishment, from that battle onward, the next concrete era in history that we know of is the "Warring States Period", in which clans fought for power and prestige, money and land, but most of all, for survival.

So now, the question remains: do you believe that the Warring States Period began right after Asura and Indra's battle? Or has there been different eras in shinobi history before the warring states era?
