Xan and Krekowis had jointly created the realm of Pontus prior to the session and wanted to give it a spin. We all created Eidolons from scratch by developing creeds and concepts, then choosing one persona trait from each of the five categories (personality, vice, virtue, drawback, talent). Four traits were set at the Superficial level, and one trait was given only a single dot of emergence.
In this session our characters were all simultaneously transported at their moment of ascension to a rocky outcropping floating in space (retconned to be part of Nexus) with a portal to Pontus. Determining that their new purpose in life was to recreate Empyrean and realizing that means to this end lay behind the portal, they stepped through.
Krekowis was a native Nascent of Pontus, so she directed the party to the grand library there, where they could learn more. After a confrontation with the living marble guards at the library entrance, the party met Sand, Guardian of Falling Library, a representative of Librarium Omnibus in Pontus. He explained that the party was meant to help uncover the secrets of the Empyrean Key recently discovered deep beneath the sea.
Omegus experimented with the key and discovered that it could be used to slice open shards of reality, exposing a world of endless stairs and bridges. After some discussion the players decided that this realm was Nexus, the center of Empyrean and home of Grand Cornerstone. Most of the rest of the session was taken up in out-of-character discussion on the nature of the realm.
