Nonhuman
sophont race found on Tsanesi (Reavers' Deep 1711), though they are not,
apparently native to that world.
Current archeological theory believes them to be a population
transplanted to Tsanesi from an unknown world of origin, probably by the Saie;
at least one school of thought credits the Ancients, but historical evidence is
against this.
The
Yn-tsai are an intelligent, civilized race, which had achieved a tech level 3
culture when first contacted by Caledonian explorers in 563. It took many decades to overcome racial distrust and fear of
"visitors from the sky" -- a remnant, most sophontologists agree, of
their memories of the devastating civil war which destroyed their Saiean
masters. The traditions of the
Yn-tsai have afforded many of the building blocks for the as yet incomplete
knowledge of the Saie.
