Before we go much further, I think it’s time for an overview of the main linguistic, religious and political developments in the study area. The three are very much intertwined. Other topics will get their own timelines when the need arises.
Dates for events are given below in the Zayedin calendar. They are expressed as years before or after the Proclamation of the Faith in the year we call 1154 A.D. In the Zayedin calendar, this is Year Zero. It inaugurates Omun Zeikan, the Age of Light. Earlier dates are expressed negatively. These belong to Omun Hemwan, the Age of Error.
The calendar counts in Base 12, represented here by Arabic numerals, plus X for ten and E for eleven. Unlike our calendar, it measures elapsed years not current ones. Dates in Omun Zeikan are therefore expressed in the same way that we reckon a person’s age, “when the Age of Faith was X years old”. Similarly, Omun Hemwan dates measure the number of full years left before the Proclamation of Faith.
Zayedin dates are followed by the approximately equivalent year in our Christian calendar. As Mohai is located on a parallel Earth, the year is the same length as ours, but Zayedin years start on the day after the Winter Solstice.
