Cycles is the term used by the people of Anvaris to define time. A single cycle consists of a hundred (100) years and after the hundred years have passed it is time for a new cycle.
The beginning of the first cycle is defined by the birth of time, as well as the birth of the gods Dekanas and Andvarus who shaped the world to what it is today.
A persons birthdate is defined by the cycle they were born in, the current year and the day of the month.
