Lyrane is a cool, moist planet, with 78% water cover and a perpetually high relative humidity.
Humans have imported larger animals. Some fish do well in the oceans and swamps. Reptiles, mammals and birds make up an extended imported ecosystem, along with dry land plants, of which Lyrane has no native specimens. In general, the native and imported life do not interact, since imported species are usually confined to the hilly and mountainous upland regions, where no native life grows or ventures.
The native arthropods are harmless to large life forms, but vigorously attack and destroy any imported creature of approximately their own size. No insect species have successfully been imported to Lyrane and established in the wild. Strict quarantine checks are made on ships leaving Lyrane to avoid any accidental export of these destructive organisms. Experts believe that, if transported to Earth for example, Lyrane arthropods could wipe out most if not all of Earth's native insect species.
Lyrane's abundance of alien plant matter also makes it an important source of exotic medicinal drugs. The mountain ranges contain large deposits of heavy metals, so such materials are quite cheap, but no company has managed to set up a profitable large-scale extraction and exporting business yet.
Lyrane's few deficiencies include light metals, which are imported in bulk, and luxury items dependent on Earthly insect life. Thus, honey, royal jelly, silk, natural beeswax form lucrative luxury imports. Also, plants which require insect pollination must be hand-pollinated on Lyrane, so several fruits are exhorbitantly expensive to produce on-world, and are sometimes imported.
Yandis and Lyratia have had periods of major tension over the past few hundred years, but no outright war. Relationships are currently peaceful, if aloof. International tourism is allowed, but not encouraged.
Both countries make independent representations to interplanetary councils. Both are on good terms with Earth and other nearby worlds.
The government of the former country of Taiwan on Earth currently sits in exile on Lyrane, in Sennier, the capital city of Yandis.
