Athshe
Athshe is a forest planet (whose name means "forest"), also known as 'World 41' and called "New Tahiti" by Terrans. Athshe is peopled by a small, furred (but in fact fully human) group of HILFs (high-intelligence life forms.) It was exploited for its timber resources before a native revolt expelled the Terrans, as described in The Word for World is Forest.
Athshe's plants and animals are similar to those of Earth, placed there by the Hainish people in their first wave of colonisation that also settled Earth. The Cetian visitor also states categorically that the native humans "came from the same, original, Hainish stock". It is not explained why they are green-furred and only one metre tall. Their sleeping cycles are also very different from the Hainish norm. There are two likely explanations. One possibility is that the original settlers were genetically modified by the Hainish. On the other hand, enough time has passed since the original settlement for the locals to have naturally evolved in response to their environment.
