Periods

The Periods are the three separate worlds that exist, including the world the Bolganio continent is set on. Since the creation of the First Period, two other worlds were created after it with distinct characteristics from each other, the last being the primary setting of the Evillious Chronicles.

First Period
Presumably the first world created. At some point, the world ended, prompting the creation of the Second Period.

Second Period
The second world created after the end of the First Period. Humans existed in the world; although a rare occurance, it was possible for unrelated humans to be born with a strong resemblance to one another, although the chance increased when they were related. The four gods, Levia, Behemo, Held, and Sickle also maintained human forms while in that realm. The ark-shaped device Sin was made during this time. Sometime afterward, the world ended, turned to deadened earth, prompting Sickle to create the Third Period. Afterwards, Sickle farmed the decimated landscape to create vast golden rice fields; he then allowed all humans, save for HERs, to be sent to the Second Period after death, dubbing it the Heavenly Yard.

Third Period
The third world created by Sickle after the end of the Second Period. Among its landmasses included the Bolganio continent and it was inhabited by humans. Interested in seeing how the world would develop and end without its creator's influence, Sickle chose to incarnate as a bat in the world and remain an observer, watching his creation's path. After the humans in the Third Period died, they went to the Heavenly Yard, save for those born with Hereditary Evil Raiser Syndrome, who went to the Hellish Yard instead.

Curiosities

 * Although the Heavenly Yard is the Second Period, it is unknown if the Hellish Yard is one or part of the previous worlds.
 * According to Held, the Second Period ended due to the mixture of good and evil; he similarly disapproved of Sickle not segregating good and evil in the Third Period.
