Magus Of Possibilities

Age of Gods:

The time period beginning with the genesis of the Earth until the beginning of the Common Era around 0 AD, during which the world followed laws based not on physics but on Mystery. This period is marked by a greater proliferation of Phantasmal Species and greater interaction between gods and mortals. This is the age of heroes and mythology, when rules of mankind and the laws of the world were different right down to the very fundamental physics of reality itself, but this period ended many years ago. Even Magecraft itself is described as being closer to Magic in this era and Caster's abilities reinforce this concept. The currently-revealed Second Age of Gods eventually transitioned into the Age of Man due to three major events.

Age of Heroes/Faeries

Not much is known about the Age of Fairies but the Age of Fairies has ended.

Age of Man:

Around 0 AD, the Age of Gods ended entirely and the population of humanity grew explosively. Because the Earth obeys the law of the most prosperous species on its surface, the rules of the world were completely changed from one that mostly obeyed Mystery to one that mostly obeyed physics. The Phantasmal Species ceded the Earth's surface to humans and moved to the Reverse Side of the World, where Mystery still thrives.

The current age is identified as the Age of Man , where Mysteries such as magecraft are dwindling in favor of science. The Five Magics were born in this age.
