Non-world

Non-worlds were locations or area of reality with no physical location in the Spiral Politic — and, as such, a source of great annoyance to the Great Houses during the War in Heaven. The three most notable non-worlds involved in this Time War were Mictlan (a realm of pure ideas, created by the Celestis to serve as their lair), the Eleven-Day Empire (a time-looped shadow-version of London serving as the base of operation of Faction Paradox) and the City of the Saved (the realm of the timeship Compassion, which stood beyond the end of the universe).
