49:3.5
On the nonbreathing worlds the animal species are radically unlike those found on the atmospheric planets. The nonbreathing plan of life varies from the technique of existence on an atmospheric world; even in survival their peoples differ, being candidates for Spirit fusion. Nevertheless, these beings enjoy life and carry forward the activities of the realm with the same relative trials and joys that are experienced by the mortals living on atmospheric worlds. In mind and character the nonbreathers do not differ from other mortal types.
