Behind the scenes
- The Eleven-Day Empire: A Tour of the Capital, a short piece written by Mags L. Halliday for the Faction Paradox website, explored the Empire in the context of the annual "Feast of Fools" pageant.
- The Eleven Day Empire is mentioned several times in the popular SCP-3999 of the collaborative SCP Foundation universe. This story features its own author (classified as "SCP-3999") as a reality-bending being which the fictional Foundation tries to contain as a metaphor for the author's addiction to the SCP community; the references to the Empire have to do with the author's sense of lost time.
