The groups going west became less contaminated with the backward stocks of mutual ancestral origin than those going east, who mingled so freely with their retarded animal cousins. These unprogressive individuals drifted southward and presently mated with the inferior tribes.

Fewer and fewer of the primitive settlements maintained the worship of the Breath Giver. This early dawn civilization was threatened with extinction.
