The Codex of Aegis Compilation consists of a wide span of content that was posted on the Codex of Aegis blog from roughly 2013 to 2016. In addition, the volume contains a large amount of content that was never released, including cut content, commentary, and exclusives. Pushed back from its intended release in 2016, the Codex of Aegis compilation is now available to the public for the first time in its history.
