Philosophers and scribes divide the history and mythology of Glorantha into various ages. When applied to the God Time, such scholarly pedantry has a certain inherent absurdity, for how can one define the eternal, nonsequential, and simultaneous God Time in terms of temporal years? However, in many religions scribes have tried to do just that and the most commonly accepted scheme is presented here along with scholarly estimates of approximately how long ago these ages were.
Third Age: 1120 ST to present. The current age, defined by the rise of the Red Moon and shall be ended by the Hero Wars.
Second Age: 500 ST to 1120 ST. Also called the Imperial Age. This was an age of experimentation, exploration, and conquest. It ended in destruction, the Closing of the Seas, and the Dragonkill War.
First Age: 1 ST to 500 ST. Also called the Dawn Age. This was an age of growth, discovery, and innocence that ended with the Broken Council, the Sunstop, and the Gbaji Wars.
Dawn: Year 0. Time began with the first Dawn. Before the Dawn was the God Time, timeless and eternal. After the Dawn was Time, temporal and changing.
Grey Age: 0 to -500 years before the Dawn. Also called the Silver Age (especially by the Theyalans). This was an age of growing light as mortals secured their survival and the world was reclaimed.
Greater Darkness: -500 to – 2500 years before the Dawn. Also called the Chaos Age. The last gods fought each other until the whole world was destroyed by Chaos.
Lesser Darkness:-2500 to – 10,000 years before the Dawn. Also called the Storm Age or the Ice Age. With the Sun gone, the Air gods contended against Sea and Darkness for dominance.
Golden Age: -10,000 to -100,000 years before the Dawn. The Sun god Yelm ruled all beneath him, but discontent and rebellion brewed at the edge of his vision until finally Orlanth contested with Yelm and slew him with Death.
Green Age: A timeless age of Creation. Powers and elements created lesser copies of themselves or mixed to create new things.
