Interspecies Defaults

Apply these defaults when dealing with a species from a Zorski Group other than the one you're specialized in. [From GURPS: MODULE PRIME ALPHA]

Zorski Group	Description	Defaults	Examples
Group I	Humans and all species moderately compatible in terms of blood and biochemistry. (Alpha-Centaurians are genetically human.)	-1 within a subgroup -2 with other Group I subgroups -5 with Groups II-IV -10 with Group V -15 Groups VI-IX	Subgroup a: Humans/Alpha-Centaurans (same species), Rigellians Subgroup b: Brecon, Cygnans, Prellarians
Group II	Species dissimilar to Group I in biochemistry and/or have significant internal organ differences including extra or unique internal organs.	-2 within Group II -5 with Groups I, III, and IV -10 with Group V -15 Groups VI-IX	Arcturians, Klingons, Tellarites
Group III	Species dissimilar to Groups I and II in that they have copper-based blood.	-1 within a subgroup -2 with other Group III subgroups -5 with Groups I, II, IV -10 with Group V -15 Groups VI-IX	Subgroup a: Vulcans Subgroup b: Andorians, Orions
Group IV	Mammalian species with biochemistries moderately compatible with Group I, but which have significant internal and external differences.	-5 with Groups I-III -10 with Group V -15 Groups VI-IX	Kzintis
Group V	Reptilian species with biochemistries and internal/external differences that are significant when compared to Group I.	-1 within a subgroup -2 with other Group V subgroups -10 with Group I-IV -15 Groups VI-IX	Suliban
Group VI	Exoskeletal species that are significant different to Groups I-V and each other.	-15 with any other species, including other Group VI species	Mynieni
Group VII	Species that do not have individual internal organs or their equivalents, and include plantlike species.	-15 with any other species, including other Group VII species
Group VIII	Species that do not breath oxygen and come from subzero (though not cryogenic, see Group IX) climates.	-15 with any other species, including other Group VIII species
Group IX	Species that do not breath oxygen and come from cryogenic climates.	-15 with any other species, including other Group IX species
Group X	Species that are highly unique and defy classification.	no default, specialization must be learned through direct experience	Tholians
