History

Non-Terragen history extends back some hundreds of thousands of years in the case of species like the To'ul'hs, or for tens of millions of years in the case of such species as the Muuh. Because of difficulties involving fragmentary records and the interpretation of xenosophont languages and psychology, some Terragen experts have considered non-Terragen history to be a field within Xenology, and do not regard it as history proper.

A flowering of artistic creativity, scientific discovery, technology and trade, together with some significant changes in the operation of personal culture, and a political ferment.

A renaissance event often sets the pattern for future cultural development in ages to follow. - Rise of the Archailects, The - Text by content by M.
