Mechanica's Factorial City

Description
A city made completely and utterly from factories and machines, this grim town harbors the will of the great Witch of Machines, Mechanica. It is old and seemingly abandoned, with many highly advanced, yet completely unused machines capable of creating anything one desires. Every building, including the inhabitable ones, are made for production of something. The entire factorial city is able to be sustained on its own, but has been turned off after the main power source, Mechanica, had been slain. Though the city no longer runs (as it needs a new power core), many of Mechanica's loyal cyborg witches still faithfully upkeep her city and themselves, protecting it from intruders and building more mechanical beings like themselves from old, unused or recycled parts.

History
After sculpting this city in her own image, legend has it that Mechanica took rogue witches in and transformed them into magical mechanical cyborgs and let them take refuge in her gloomy city. Soon, a young weapon named Tear Lacrimoso made his way to the factorial town and slayed the great Mechanica, taking her soul to become a Soul Angel. Rumor has it that her Witches still inhabit this city, however, as well as many of her other mechanical monstrosities...

Completely metallic or grated streets and many fences or thick steel walls litter the entirety of the factorial city, making it look like some sort of engineer's wildest dream. With pipelines, railings and tracks everywhere, it looks like a mix between an underground train station and a large boiler room in most areas of the city. The buildings look like factories in and of themselves, and in fact, most are. The cyborg witches that live here are capable of generating their own miniature factories that serve as their homes and producing small things that are necessary for themselves, even if the entire city as a whole is shut down in terms of mass production. Though old and abandoned, it's surprisingly well kept.
