What is Fallen London?

"Fallen London: once capital of the British Empire, now home of the Bazaar. Deep. Dark. Expensive. Marvellous. Here you can find everything from immortality to unnervingly good mushroom wine."

Fallen London, Sunless Sea, Sunless Skies, and The Silver Tree all take place in an alternate-history scenario in which five major cities in succession (eventually, there will be seven) fell underground into the vast network of caves known as the Neath. The first two games take place in the 1890s, approximately 30 years after London became the fifth city to fall, and are set in and around the new, convoluted London.

Sunless Skies takes place in 1906; Londoners have managed to figure out space travel ten years after Fallen London and Sunless Skies, and has launched itself into a sky where the stars are mysteriously dying out...

The Silver Tree takes place in the Mongol Empire in the 1200s, as half its capital is about to become the Fourth City and the other half's refugees are about to start a floating empire in the Neath.

A Note from the Founder

I'm not a moderator or admin of any Failbetter game, or an employee of the company. I just happen to enjoy games with tons of lore, like Fallen London, and was a bit disappointed when I found that there wasn't one single place for all the lore for this amazing browser game.

So I made it. This is that single place. Feel free to create a page on a character, place, or event in the alternate history of the Fallen (and Falling) Cities. Be aware that some content (for example, Fate-locked or mind-blowing snippets) may need to be given a spoiler warning or redacted; check out this page to get the templates and/or code for both spoilers and citations.

Have fun, delicious friends!
