Two vast stalactites, containing a third suspended between them, like an embrace. One is misshapen and ungainly, one smaller and ovoid. The third is like a knife, aimed down, down below.

The first chapter of Firmament is here! Journey to the Roof to unravel a mystery long in the making; uncover new locations, conflicts and intrigues that speckle the Roof like the false-stars; follow fire, and save yourself from what comes after.

Firmament is Fallen London's next major expansion, a main story arc that's free to all players. It begins once you have progressed the Railway story arc as far as Ealing Gardens.

As part of this first chapter, you'll also unlock the citadel of Hallow's Throat, a new location on the Roof. Traverse the Lung and Spleen. Reshape yourself. Water your new throat at the Arms.

To begin Firmament, look for an opportunity card in your deck. For those who've completed the prologue, look for the air to clear, anywhere in London.
