The registration form creates a new star system in a selected parsec hex. Enter a name, choose a hex (if not already selected from context), and pick one of three initialisation modes. Press Commit Core to create the system.
Initialization modes
- Empty
- Creates a star system with no orbital bodies. When this mode is selected you configure the primary star by choosing a spectral type, subtype, and luminosity class. A primary star is required for a star system.
- Use this when you have existing star systems you want added to the app.
- Random
- This option generates a fully populated star system with stars, orbital bodies, and a main world. No additional input is needed.
- Use this when you want a complete system quickly and don't need control over its composition.
- Build configuration
- Accepts a YAML configuration that tells the generator how to construct the system. You can specify the primary star and its companions, orbital body counts or density, allegiance, bases, and individual orbital bodies with specific UWP codes.
- Use this when you need a generated system but want to constrain some of its properties. See the star system build specification for the full YAML reference.
Primary star fields (Empty mode)
- Type
- The spectral type of the star: O, B, A, F, G, K, or M. Special types (Brown Dwarf, White Dwarf, Black Hole, Pulsar, Neutron Star) are also available, as are the L, T, and Y brown dwarf classes.
- Subtype
- A digit from 0 to 9 that refines the spectral type. Lower numbers are hotter within the class. Not required for special types; still required for L, T, and Y.
- Luminosity class
- The size classification of the star, from Ia (luminous supergiant) through VI (subdwarf). Main sequence stars are class V. Not required for special types or for L, T, and Y.
Travel zones
A travel zone classifies the hazard level of a star system. Two standard zones are pre-installed in every campaign and cannot be removed:
- Amber
- Systems requiring caution — unusual conditions, unstable governments, or other elevated risk. Displayed as an amber ring on the subsector map.
- Red
- Systems interdicted or extremely dangerous. Travellers enter at their own considerable risk. Displayed as a red ring on the subsector map.
Additional zones may be defined under Data Cores → Travel Zones. A zone can be assigned to any star system from its show or edit page, and is automatically set when importing from TravellerMap.
