Known Biomes

Biocompatibility Rating Scale

1.0: Derived from Terran rootstock. Examples: Earth, Zoo, any human-terraformed world

0.9: Close biochemistry, may have some intrinsic poisons or lack of nutrients. Atmosphere will be breathable with no problems. Examples: Londenium, Kanon

0.8: Divergent biochemistry, though manageable with appropriate supplements. Atmosphere will remain breathable. Examples: Van Lang

0.7: Strongly divergent biochemistry; substances will be poisonous and/or provide no nourishment. Atmosphere may not be entirely breathable. Examples: Haraway

0.6: As rating 0.7, but atmosphere is poisonous and requires breathing apparatus. Examples: Pandora (from Avatar)

0.5: Atmosphere is poisonous upon skin contact.

0.4: Negligable biosphere but atmosphere is relatively benign. Examples: Erebus

0.3: Negligable/no biosphere with unbreathable atmosphere. Liquid water exists on the surface. Examples: Adhara

0.2: Negligable/no biosphere with unbreathable atmosphere. Liquid water can exist outside but is not common. Examples: Theia

0.1: Negligable/no biosphere with deadly atmosphere/climate. Full environmental protection required. Examples: Mars

0.0: No biosphere, no atmosphere of mention and/or hostile climate. Titan, any asteroid.

Common Biomes

Terran

Biocompatibility Rating: 1.0

Known Worlds: Earth, Zoo

The Precursors spread Terran-derived life to an unknown number of worlds. To date, three have been discovered.

Asakuran

Biocompatibility Rating: 0.9

Known Worlds: Kanon

The planet Kanon had naturally-evolving life which has been found on two other worlds. While similar to Terran life, 'Asakuran' biology tends towards brightly-colored pseudoavians as its dominant lifeform.

Livenan

Biocompatibility Rating: 0.8

Known Worlds: New Mercia

The Livenan metabiome seems to have originated on the moon of a greenbelt gas giant, as all examples of this family are on inner-system gas giant moons. Favoring somewhat less radiative flux than Earth, they are generally characterized by cold, often ice age conditions and life adapted for this.

Eruban

Biocompatibility Rating: 0.4

Known Worlds: Erebus

Unfortunately, Livenan metabiomes appear to have been put on relatively marginal worlds and in several cases they suffered a complete biological collapse into an 'icebox' status, leading to the extinction of all life more complex than bacteria. However, with proper tools they can be habitable again.

Harawayan

Biocompatibility Rating: 0.7

Known Worlds: Haraway, Whileaway
