Polynesians

Polynesians are the indigenous population of Polynesia. They were a seafaring people very early in history, and traveled to numerous places in the Pacific Ocean.

One tribe traveled to Antarctica -- finding it unusually warm with an abundance of life around a meteorite that had landed there. This tribe built a colony around the meteorite, and remained there, constructing a city around it. However, when the women of the tribe gave birth to deformed children, the tribe abandoned their city and fled -- leaving the artifacts they had carved from the meteorite behind.
