This is a list of the fictional planets in the Humanx Commonwealth series of novels by Alan Dean Foster.
Alaspin has large jungles surrounded by equally large savannas and river plains; its only notable celestial feature is two moons.
Currently the planet has no sentient race; the native race died out, possibly by racial suicide, over 75,000 years ago leaving behind hundreds of ancient, abandoned cities that have proved a source of fascination to modern xeno-archaeologists.
A variety of lifeforms currently live on Alaspin, most notably the Alaspinian minidrag.
Annubis is most notable for the fictional Hyperion forests from which the fictional drug bloodhype is manufactured. In an attempt to eradicate the highly addictive and deadly drug, the trees were burned in 545 A.A. and are thought to be completely destroyed.
The planet first appeared in the novel Bloodhype.
Blasusarr is the homeworld of the AAnn race and is often called the Imperial Home World. Climate is dry and hot, largely desert, the preferred atmospheric conditions of the AAnn. Beyond this, little is known about Blasusarr other than the fact that it is very well-protected by a detection and space defense network. Its capital city, also the capital of the AAnn Empire, is Krrassin.
Cachalot is almost entirely covered by ocean with small ice caps and a few artificial floating islands created by humans. The dominant non-native races are intelligence-enhanced Cetacea (includes whales, dolphins, orcas and porpoises) that were brought to the planet from Terra in 2300 A.D. The name of the planet derives from the Portuguese word cachalote, a common term for head. This word was applied to the sperm whale, for its large head, when the mammals were actively hunted in Earth’s oceans.
The novel Cachalot (1980) introduced the planet to the Humanx Commonwealth universe.
Hivehom is the home system of the thranx race; the system itself has twelve planets, four of which are inhabited.
