The spirit in the Relic of Creation, Ambrosius is capable of creating anything as long as he gets a detailed description of it.
Team RWBY showed him blueprints of the Snow Shoe Shipping shipment system as a base for the evacuation system. The pocket dimension is similar to Vaults as it doesn't have a true physical location.
The location consists of long spiraling pathways across an empty void. The void surrounding it is a deep shade of blue, with each of the bridges being a yellow color. Many of the bridges converge to different circular shaped platforms, each being a deeper shade of yellow.
Many portals connected to locations in Atlas are scattered throughout the location, being oval-shaped with a yellow border and light blue insides. These portals are located on the smaller sized circular platforms. The single portal connected to Vacuo is much taller than the Atlas portals, and is located on a large platform connected to many bridges near the back of the location.
Due to Weiss's statement that the evacuation would be a "one-way ticket from Atlas to Vacuo", Ambrosius took this literally and made the single portal to Vacuo one way. While it is possible to travel through the other portals to the other locations of Atlas and Mantle, anyone who attempts to travel back through the portal to Vacuo back to the central hub is blocked and is unable to pass through.
They used Penny, the Winter Maiden, to unlock the Atlas Vault and access the Relic of Creation to summon Ambrosius. After asking him to save Penny, Team RWBY then explain that they would like him to create portals throughout Atlas and Mantle that will all lead into a pocket dimension similar to the Vault. From there, everyone will be able to travel to a singular portal that opens into Vacuo. With the logistics explained and maps presented to him, Ambrosius makes it so, and just before they enter the portal near them, he warns, “Do not fall”.
As the evacuations take place, Cinder Fall and Neopolitan attack Team RWBY, Penny, and Jaune Arc. During the fight, Team RWBY and Neo are knocked into the void, through Neo and Cinder's efforts, and Penny is mortally wounded by the latter, being killed by Jaune. Winter Schnee, having inherited the powers, attacks Cinder but is forced to retreat as Cinder makes her leave with both the Relics in hand. Cinder dispels the location, removing it to bring more flames to Atlas. During this, Jaune also falls into the void as the Evacuation Location is destroyed.
It was later revealed that when Crescent Rose fell into the void, it was sent to a mysterious shore with a giant tree overlooking it.
Ever After is named after the ending phrase from Fairy Tales. Many fairy tales ended by saying that the characters in the story lived happily ever after.
The design of Ever After could be an allusion to the yellow brick road of The Wizard of Oz.
