The Cindergate

A descent that pays straight back into whatever a character has already spent hundreds of hours on

A basalt arch straddling a lava vent, standing wherever a player happens to breach into Hell — Hell has no map and no fixed frame, so the Cindergate is found by descending rather than by hunting a coordinate, and it's the one single built thing at the floor of the world. Before it existed, two of Hell's four materials — Soul Coal and Bottled Hellfire — were consumed by nothing anywhere in the game, dropping from hell knights and imps and simply sitting in the pack forever.

Getting there at all means digging straight down with a Mining Drill until your depth reading passes 1,000m — there's no other entrance. The game marks the transition plainly ("You breach the floor of the world. This is HELL.") and the Cindergate always appears a short distance from wherever you actually broke through, since Hell has nothing to place it against.

Cast, seat, then draw

The Cindergate follows the same three-step shape as several other stations built across the game:

1. Cast. 6 Brimstone and 2 Soul Coal bank into a Cinder Core — the first consumer Soul Coal has ever had in the game.
2. Seat. A core drops permanently into one of the gate's three sconces, and the Cindergate visibly shows how many are lit from a distance.
3. Draw. With at least one sconce burning, Bottled Hellfire can be drawn off as Fuel Cells — each bottle yields 2 plus 1 per sconce lit (3 with one sconce burning, up to 5 with all three).

Interacting with the gate always resolves the single most useful step available: seat a carried core if there's a dark sconce and one's in hand, otherwise cast a new core if any sconce remains dark, otherwise draw off any carried hellfire if the gate is burning. With every sconce already lit and no hellfire on hand, casting still produces a core anyway — it cools loose on the bed and is worth carrying up regardless.

Why the payoff isn't a fourth isolated loop

Fuel Cells are the widest sink in the entire game — burned by the mining drill that got the player down to Hell in the first place, every aircraft, bombs, and the Mk2 rocket the whole Moon / Vulcanis / supply-pod chain depends on. So a descent into Hell pays straight back into systems a character has likely already spent hundreds of hours building up, rather than creating one more separate reward track to manage on top of everything else.

Version history

• The Cindergate added, giving Hell its one built landmark and turning two previously dead materials — Soul Coal and Bottled Hellfire — into the game's own Fuel Cell economy.

Trivia

• Part of the same "cast, seat, then draw" family of stations as The Pauper's Pyre, The Meltwater Still, and The Ashfall Kiln — each one built at a different dead-end location, solving a materials problem specific to wherever it stands.
• Sconces lit at the Cindergate are permanent for that character and remembered across visits — the gate reminds a returning player exactly how many are still burning the moment they come back down.
