The Acheron of Nappa (Diaspora 0932) are a Human Chimera with a humanoid appearance and technologically developing sophonts.

Description (Specifications)[edit]

The Acheron were genetically engineered during the Interstellar Wars period to exploit the mineral wealth of their homeworld. They are considered ugly by human standards, but stronger, tougher and more resistant to high radiation levels.

Climate & Ecotope (Environment)[edit]

This species holds the following environmental preferences:

  • Terrestrial type of planet
  • Cold climate
  • Barren plains ecotope
  • Standard gravity range
  • Standard atmosphere with a taint
  • Increased radiation hardiness

Anatomy & Physiology (Corporeality)[edit]

Sophontologists studying this species have discovered the following data.

Body Plan (Appearance)[edit]

  • Humanoid
  • Bilateral symmetry (2-ial)
  • Tetrapod (4-ped)
    • Two limbs used for manipulation "arms"
      • Former brachiator (still capable climber)
    • Two limbs used for locomotion (biped) "legs"
  • Body consists of three segments
    • Head with sensors and multiple-use orifice (consumption, communication, and respiration)
    • Torso with manipulatory limbs
    • Abdomen with locomotor limbs

Biochemistry (Function)[edit]

Acheron have a conventional carbon-water based biochemistry hardened to survive in a high radiation, atmospherically tainted environment.

Respiration (Reaction)[edit]

Acheron use a conventional respiration cycle consisting of:

  • Oxygen-nitrogen inhalant
  • Carbon dioxide exhalant
  • Taint filtering

Ecosystem & Population (Ecology)[edit]


  • Hyper-acclimitization: Known to quickly adapt to many different climates and environments.
  • Requires shelter and clothing.
  • Prefer to shelter in defensible dens protected from the elements.

Diet & Trophics (Consumption)[edit]

  • Omnivore/gatherer
    • Homeotherm
    • Sometimes called a "hunter-gatherer" due to many human's penchant for pursuing animal sustenance.

Gender & Sexuality (Reproduction)[edit]

Acheron have the following reproductive characteristics::

  • Two genders (male & female)
    • Mild sexual dimorphism
  • (sexual reproduction)
    • Reproduces through conjugal intercourse
    • Varied mating systems (primarily monogamy)
  • Viviparous birth
    • (Iteroparous): Uses K-selection and have few offspring that require considerable amounts of time to raise to maturity.

History & Background (Dossier)[edit]

Evolution & Environment (Development): This species originated on Acheron (world) as a geneered version of Humaniti, a Variant Human Race.

In -2202 the first Acheron-nu individuals reached maturity. The colonists were trained by Terran scientists, who informed them of their special origins and purpose. Engineers, advisors, and counselors mentored them for a few generations, giving them medicine and supplies in return for metals. Then one day they flew off, never to return.

In 387, merchants from a nearby world discovered the existence of the Acherons. The Acherons were willing to trade minerals for manufactured goods, as they had done centuries before. For their part, the offworlders were quick to recognize the opportunity for tremendous profit. They worked from the abandoned Second Imperium space station, which they expanded into an orbital port. In order to protect their advantage, they kept the very existence of the Acherons a secret. They also carefully avoided giving the Acherons any independent spaceflight capability. This situation lasted for centuries.

In 991, an Imperial Interstellar Scout Service ship crash-landed and brought its crew into direct contact with the Acherons. The Acherons were appalled to discover the degree to which they were being lied to and exploited, and decided to emancipate themselves. Somehow, they sneaked onto the highport, took control, and aligned their world with the Imperium. Acheron fighters clamored to serve the Emperor, and did so with such distinction that the Imperial Navy named an Azhanti High Lightning-class cruiser after them.


This race is primarily located in the following areas:
