Remnant: The Last City
Stands for Elder’s Salvation.
This is the mark from which the people of Remnant mark the passage of time. Time began being tracked using ES from the day of the Great Calamity. Though the campaign begins on May 14, 457ES most people understand that this is not the correct date. During the Wood Rebellion the Time Keeper was killed and it was not until after the rebellion ended that a new one was found. In addition there is some concern that the method of marking the passage of time in the city is fundamentally flawed and thus the date is even more askew than most people realize.
