The structure is located within the atmosphere of the class J gas giant Cherela, held aloft by a complex antigravity system powered by the planet's electromagnetic field. Each world module is continent-sized, at least 1,000 kilometers in diameter. Segments are arranged hexagonally, with a combined surface area approaching half that of the combined worlds of the Federation.
The Web is a haven and refuge for citizens of the First Federation, all of whom were being hunted by Dassik. The modules recreate and preserve planets destroyed by Dassik mass drivers 12,000 years ago. Rather than having a centralized capital, the government relocates seasonally, providing a measure of equality for its members. All member races have at least one world module with the exception of the Linnik, who preferred to live underground spread across a variety of modules. (TOS novel: The Face of the Unknown)
Circa 9700 BC, the first modules of the Web of Worlds were built and settled.
In 2267, the USS Enterprise discovered the Web of Worlds while attempting to evade a group of Dassik vessels. While the existence of the metropolis was revealed to the Dassik, negotiations for peace also began. (TOS novel: The Face of the Unknown)
