The Cauldron Nebula is a reflection nebula located within the heart of Cauldron Sector, within the Where The Stars End region of the Empty Stars.
- It is an astrographic feature and a nebula.
- It is part of Uncharted Space.
Description (Specifications)
The Cauldron nebula is a large group of bright nebulae and dark clouds measuring around 20 parsecs coreward-rimward by 15 parsecs spinward-trailing.
- It is classified as a reflection nebula and is primarily formed of ionized gases, thrown off by the giant stars at its center many millennia ago.
- The gases consist of about 90% molecular hydrogen (H2), with the remainder made up of varying concentrations of helium (He), oxygen (O2), nitrogen (N2), and other elements. The clouds have a mean density of 102–106 particles/cm³.
It is considered to contain 26 separate stars of varying ages grouped into ten separate star systems. These include x2 Bright Giants, x6 Giants, x5 Subgiants, x11 Main Sequence, x1 Subdwarf, and x7 Dwarfs.

System Diagram:
A basic astrographic chart of the Garazal system, lying in the the heart of the Cauldron Nebula.
System Components:
x4 planetoid belts, no other significant bodies.
- Three vast belts, made up of fine particles and divided by ill-defined transition zones, lie around the primary star. The inner belt is largely made up of metallic and stony materials, the outer belt contains a higher percentage of frozen volatiles, while the middle transition zone belt is a mixture of the two and contains the largest individual bodies, some weighing as much as a few grams.
- A broad belt made up of fine particles orbits the distant binary pair companion stars.
The transition zone belt orbiting the primary star is nominally the mainworld.
- Mainworld UWP: ?000???-? As Va
Astrograpic Dangers
The Garazal system is considered a hazard to navigation and health and is classified as a Red Zone:
- A miasma of molecular particles sleets through the system. This interferes with communications and sensors.
- Occasionally, a particularly dense pocket of material may gain enough static charge to trigger a powerful plasma discharge.
- Radiation levels within the inner system are significantly elevated, rising to as high as 300 Rads per hour.
- Both of the companion stars are Flare Stars and are active EM transmitters.
