Perhaps ordinary people still didn't know about the battle of Hell yet. However, this battle had such far-reaching influence and great impact that it was destined to enter Eich's history books.
A new third major faction arose for the first time ever in the eternal war between Order and Chaos. The Order Faction was split as several powerful Order Gods joined the Hell Faction and became Hell Gods instead. The Chaos Faction lost Cynthia, the will of the Chaos Abyss, and several Chaos Main Gods. Naturally, neither Order nor Chaos came out as a winner in this. But amongst all the losers, there was one smaller faction that lost by far the most. That would be the devils.
The oldest devil leaders all betrayed Chaos, with four of the nine Devil Lords switching sides and taking more than half of all Immemorial Devils with them. Since these devils had all survived countless eons until today, these were the most elite and strongest devils.
