It gleams like the fires of Hades, a tangle of steel and glass. Its potency is magnified by its failure: piles of melted girders, charred machinery and ash surround it, like a hoard spilling around the flanks of a sleeping dragon. Something impossibly grand was attempted here.

Firmament Chapter Six has arrived! Travel to the heights of the Roof to source a weapon to bring about ruin upon the Vulgate. Scour the tombs to unearth your enemy, forge a machine from the Red Science and liberate Burgundy from the golden army of Zenith while planning a daring counter-attack from an unexpected angle.

Firmament is Fallen London's current 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, although will require more progress in the Railway as chapters progress.

As part of this chapter, you'll unlock permanent access to a new location: the Sous, a bone-clogged labyrinth of catacombs festering under the Surface. Delve deep into its osseous secrets, and discover what has been lost in the layers that separate the Neath from the lands above.

Progress in the chapter will also uncover a new ally in Lost Time: the Graven Apostate! Their acquaintance is a dangerous one; they move through the Stacks without heed to noise, and often catch the wardens' attention.

Continue the story of Firmament from Burgundy. If you've not yet begun Firmament, look for a card in London named 'The Fire in the Looking Glass.'
