Eagle's Empyrean
"A neon blaze in the dark: the Eagle's Empyrean! Once they were allies of London. Today, the relationship is more nuanced."
"Seat of the Eagle Khan, at once an ally and rival of distant London."
"The Khans have always been more suspicious of devils than London was." -The Repentant Devil

Before the doors to the heavens were unlocked, Londoners and Khaganians worked together to open the Avid Horizon. London established Albion by replacing its star, but the Khaganians saw no need for such drastic measures and established Eagle's Empyrean in Eleutheria.
Ruled by the Eagle Khan, Eagle's Empyrean is the only place in Eleutheria that is filled with light. The Khaganians, who now call themselves the Empyreal, have to defend their light from Liberation symphatizers. In addition to that, the settlement is already surrounded by the Belt of Midnight, a light-consuming black hole that's already shrouded an Empyrean outpost in darkness.
Albion has established an embassy here, though they are in an intelligence war with the Rose-Without-Thorns, the Empyreal security agency. Under a treaty, the transit relay to the Reach is under Empyrean control.
The Xanthous Moon
The Empyrean have built a homemade moon to light their corner of the sky; its steel frame festooned with lamps.
Just as Londoners built an artificial Sun, the Empyreal built their own artificial Moon. But rather than use Red Science and machinery, they simply made it out of lanterns.
