Far above, a strip of silver coils around the root of a stalactite, a long fang of rock that juts down toward the zee. Beneath, a vast whale hangs belly-up and speared upon its point. These are the Harpoon and the Leviathan, forming, where beast meets stone, the improbable cradle of the Midnight Moon.

The second chapter of Firmament has arrived! Journey to the Midnight Moon to hunt the source of the rain plaguing London. Heed the calls of the Candle-Men and ambergris miners, and enter the belly of the beast.

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 chapter two, you'll also unlock a new Roof location – the Midnight Moon – where you can ply the Midnight Trade. You'll also unlock a major new activity.

Continue the story of Firmament from Hallow's Throat. If you've not yet begun Firmament, look for an Opportunity Card in London.
