Lebenswelt
Lebenswelt was an Earth colony with vast wealth, due to various deals made with Galactinationals. The Museum of Locks was located on Lebenswelt, specifically in its largest city (also known as Lebenswelt).
Despite the extreme wealth, the streets of Lebenswelt were filled with grime and decay due to the apathy of the people towards cleaning their planet (who largely only existed to party). Spires, turrets, and belfries were common architectural features on Lebenswelt.
Though objects of extreme opulence (such as jewelry) were tossed out by the people of Lebenswelt on a daily basis, taking those jewels from the pools of filth on the street was considered a crime worthy of the death penalty by the Lebensweltian government.
Native to Lebenswelt was a species of red, bat-like creatures that fought with each other in the skies of Lebenswelt.
History
According to the Doctor, five hundred years before he and his companions arrived on Lebenswelt (presumably in the 36th century), the mineral wealth of the planet was sold to a Galactinational. This led to the planet becoming one of the most opulent human colonies by the 41st century. (PROSE: The Book of the Still)
