Dark Age

The **Dark Age** was a period in Echelon's history characterized by the global Null event that claimed over 180 million lives across 12 centuries. It began with the defeat of Vecna by the Determined in the Ultima War, and ended with the Passing in 1205 DA.

## Abandon of the ACS

The According Calendar System was abandoned in 3 DA, as temporal indicators like "day" and "night", as well as seasonal indicators like "summer" or "winter" were rendered obsolete by the Null. The Historical Preservation Society-- which was later renamed after their founders-- created the Bureau of Chronography to come up with a system of timekeeping that did not rely on cosmic or seasonal changes. The Chronographer's Calendar was the result.

## Notation

According to the most widely-used Chronographer's Calendar, days were measured in three 8-hour cycles, and years were portioned into four quarters of 91 days, separated by colons in the common tongue. A specific date would read year:quarter:day:cycle:hour (e.g. 206:3:81:1:7, indicating the eighth hour of the first cycle of the eighty-first day of the third quarter of the two-hundred and sixth year of the Dark Age), with each colon separating a progressively more accurate subset of timekeeping.

Many dates only held four or even three numbers, indicating the relative loss of accuracy and unavailability of information of local time in the Null. Clockworks were used as a means of telling the exact time; however, personal chronometers were prohibitively expensive and needed re-calibration with a Master Chronometer in a Light City whenever possible. As Chronographers would rarely travel the dangerous Null, knowing the exact time was something of a luxury in the Dark Age.

It wasn't until the Light Age and the New Calendar that the abbreviation "DA" was used to indicate Dark Age time-frames, instead of the cumbersome CC system.
