Garden Worlds

Several natural Garden Worlds in the Terragen Sphere. Clockwise from top left; Menexenos, Macrystis and Lontis, Trees, Earth, Fuego, Tanhauser and Samael

Also called Macrobial, Macrobiotic or Macrobiological Worlds, these worlds are life-bearing planets with a complex biosphere and macroscopic life forms. Naturally evolved garden worlds are rare; most garden worlds within the Terragen sphere have been engineered by Terragens or xenosophonts. Worlds with primitive unicellular, protobiotic or noncellular life are generally not considered to be garden worlds.

The term 'natural garden world' is sometimes reserved for worlds with biospheres that have evolved without any known interference since the planet's formation, although natural garden worlds which have been minimally altered in the distant past by various xenosophonts are often still included. There are currently 3560 natural garden worlds within the Terragen Sphere.

List of xeno-engineered garden worlds

Many worlds were transformed into garden worlds long ago by xenosophont agencies. In the Terragen Sphere, such 'xenoformed' worlds are somewhat more commonplace than naturally-evolved garden worlds, but they can usually be distinguished by examination of the fossil record and by molecular and genetic analysis. Many of these worlds are related to each other, the relation of which can be found by tracing back the lineage, dating the biosphere, and simulating each star's trajectory to see if they all converge at one point. There are 4,881 xenoformed garden worlds within the Terragen Sphere.

List of former garden worlds

Garden worlds are fragile. The slightest disturbance can bring the end to the reign of the complex life over their world. Far more numerous than the garden worlds are these former garden worlds, worlds where the biosphere had succumbed to the elements over time. Some suffered natural destructive events such as the brightening of the local star or devastating asteroid impacts. Others were artificially destroyed, whether deliberately or accidentally. Xeno-engineered worlds are often more susceptible to environmental failure; less than optimal candidates often fail over a relatively short amount of time, becoming uninhabitable to complex life, or even losing their entire biospheres altogether. There are at least ten thousand former garden worlds within the Terragen Sphere.
