In the Footsteps of Those Who Came Before
On the morning of the Leaving, the Firsts awoke and found no evidence that the Guardians had ever existed. It is the day the Firsts were made to fend entirely for themselves. Many warrens perished outright within the first several months. Any survivors of these warrens became Walk-Abouts or were incorporated into other warrens. For the first several cycles after the Leaving, there was a huge increase in exploration and battles as warrens looked to secure resources and protect themselves.
Now, the Leaving is marked every cycle with a subdued festival mourning the loss of the Guardians, innocence, and the thousands of Firsts who have perished.
