The Werel-Yeowe solar system consists of 16 planets orbiting a yellow-white star (RKtamo554434). Life developed on the third, fourth, and fifth planets. The fifth, called Rakuli in Voe Dean, has only invertebrate lifeforms tolerant of arid cold, and has not been exploited or colonized. The third and fourth planets, Yeowe and Werel, are well within the Hainish Norm of atmosphere, gravity, climate, etc. Werel was colonised by Hain late in the Expansion, within the last million years. It appears that there was no native fauna to displace, as all animal lifeforms found on Werel, as well as some flora, are of Hainish derivationYeowe had no animal life until Werel colonised it 365 years BP.
