Tulkas Clocrolis Gremar
 * Tulkas is a terrestrial world with a thin atmosphere of methane and argon. Its frozen surface is mainly composed of basaltic rock. Its most prominent feature is the Ellos Rift Valley, a long volcanic divergence zone that stretches across half of the northern hemisphere.
 * Clocrolis is a modest rock planet, roughly the size of Mars. It has a thin atmosphere of carbon dioxide and ethane. Its scorching hot surface is mainly composed of silicate rock with deposits of aluminum and other light metals.
 * Gremar is an icy terrestrial world with a thin atmosphere of carbon dioxide and krypton. Its surface is mainly composed of frozen ammonia with deposits of tin and other light metals.

Veyaria
 * When exposed to sunlight, Gremar's ammonia can melt, forming equatorial seas of the toxic chemical. This allowed a profusion of simple fungus and lichens to evolve in the low-energy environment.
 * Veyaria is a huge hydrogen-helium gas giant with traces of methane in its atmosphere.
