Native Lifeforms

The largest living thing on the surface is the Akenplant, a cactus like growth surviving on the surface. The roots of the Akenplant can split rocks to enable the plant to survive in unlikely places, and its byproducts are exploited by the locals.

History & Background (Dossier)

The whole population of Lydia live in a single enclave, carved out of a natural cavern system. The Lydians are known for creating archaic yet surprisingly reliable life support systems at TL–6. These machines are barely sufficient to maintain the colony's trace atmosphere, but may utilize divergent technology, like one may expect from a culture surviving in such a niche.

Formerly a mining colony founded to exploit massive quantities of silver, it has been on the decline since the silver gave out around 1020. ConTech closed the starport in 1035, and most of the population emigrated. The remainder are expert garbage pickers--a fair amount of useful salvage at TL–12 remains from the mining operation, enough that free traders occasionally call to pick up the junk.

Trivia

Lydia is on the very bottom end of a "Population 4" planet, having just barely 10,000 sophonts.
