The Sun is the central stellar body of the Solar System, a near-spherical mass of plasma once categorized as a G-type main-sequence star (yellow dwarf). It historically functioned as the primary source of energy for all known REALSPACE life forms and maintained gravitational cohesion of the planetary system. However, following the Ashen Winter Incident, the Sun underwent a series of anomalous physical and energetic transformations.

Characteristics

Post-AWI, the Sun experienced a complete alteration of its visual and spectral profile:

  • Its formerly yellow-white incandescence was replaced by a pure black appearance, lacking any visible plasma behaviour or radiative corona.
  • Despite this transformation, the Sun continues to emit light, maintaining global daylight conditions and contributing to residual energy intake on Earth.
  • It is now safe to observe with the naked eye, producing no optical or thermal harm, a property previously impossible under REALSPACE solar physics.
  • The Sun is thus newly classified as a Black Star.

Impact

Alongside its visual transformation, the Sun underwent a measurable decline in harmful solar radiation:

  • Ultraviolet, gamma, and X-ray output dropped to non-hazardous levels, despite Earth’s partially collapsed magnetosphere.
  • This unexpected suppression of high-energy emissions is one of the primary factors contributing to the partial survivability of Earth’s biosphere post-AWI.
