These are the eras of the world.

Ancient World (Time immemorial-500 BC)
This era was the age of the African  Empire. The world lived in prosperity, back before the Amazonian Monkeys were much more than squabbling tribes. Around 550 BC, Helus, the equivalent of Hekate (with more lunar power and less sorcery), betrayed the other gods. His followers, the Cult of the River Tigris, struck out at the worshippers of Atenkahn and Ninja Kiwi, as Helus slayed the god-prince Zion. Over 10 years, the gods were leaderless, until Atenkahn finally became the king of all gods. Helus struck at Atenkahn, but was not ready for him. Atenkahn evened the odds by controlling the sun to make a lunar eclipse. Atenkahn trashed Helus, but had forgotten about his cult. Over 50 years, Atenkahn exiled all of the followers to the new dimension, turning them to Bloons in the process.

Prosperous world (499 BC-51 AD)
The African monkeys wore on, but the war had brought out old tension, and the newly formed empire of Japana conquered each province in quick succession. But gods are gods, and Japana worshipped the same gods (although to them, Ninja Kiwi was the king). Atenkahn and Ninja Kiwi fought for the title after this, and it ended with the Solar Emperor accidently killing the ninja. Funny thing, though; when Ninja Kiwi died, he left a flock of fledgling Ninja Kiwis, and some blueprints. Japana was shocked by this, but ushered in 400 years of greatness, until Horus the Avenger attempted to remake the African empire. Horus was the first agent of the Sun.
