Demon's Eye Nebula
The Demon's Eye Nebula is a bright emission nebula located in the center of Far Home Sector, within the Distant Fringe.
- It is an astrographic feature and a nebula.
Description (Specifications)[edit]
The Demon's Eye Nebula is a relatively compact group of luminescing gases and dark clouds centered in hex 1621 of Far Home Sector. It measures around 4.5 parsecs coreward-rimward by 4 parsecs spinward-trailing. The Demon's Eye system lies at its core.
Composition[edit]
It is classified as an emission nebula and is primarily formed of ionized gases, thrown off by the supergiant primary star of the Demon's Eye system many millennia ago.
- The gases consist of about 90% hydrogen, with the remainder made up of helium, oxygen, nitrogen, and other elements. The clouds have a mean density of 102–106 particles/cm³.
- The gases primarily emit red light, though other colors can be seen: the source of ionization is high-energy photons emitted from the Demon's Eye supergiant star.

Appearance[edit]
To the naked eye, the Demon's Eye Nebula appears as a glowing reddish-white haze in the sky with the intensely luminous Demon's Eye supergiant star at its center: the star is clearly visible, even in daytime skies. Optical instruments can pick out individual regions of denser gas and dust, swirling trails and streamers of material, clouds and billows, towering columns and cavernous hollows, and many other gigantic structures and formations. The region of gas immediately around the central stars emanates red light, though its soft glow is drowned by the extreme brightness of the star.
History & Background (Dossier)[edit]
The Demon's Eye Nebula and the supergiant star at its center, and the Demon's Eye Rift that it lies within, have been prominent features of the Distant Fringe since it was first settled.
Why the Terrans, seeking to hide from their Vilani pursuers, should choose to settle a region with such a bright beacon at its center is something of a mystery. Some hold that it proves that the Last Armada was at the very limit of its endurance and was forced to halt, while others contend that the location was deliberately chosen in order to give any potential stragglers from the Cripple Fleet somewhere to aim towards.
