Abbreviations and Terms (Guide)

Like any game, Fallen London has developed its share of jargon and abbreviations which might confuse newcomers.

Here, an attempt is made to provide definitions for the most common terms and abbreviations encountered on this wiki, the Official forums, the Reddit forums, the Official Discord, the Community Discord, or the IRC (Internet Relay Chat)

FBG & games

FB/FBG

• Failbetter Games: The developers of Fallen London.

FL

• Fallen London: The game. Was once called Echo Bazaar (EB/EBz).

FL-specific game mechanics/concepts

FLPC

• Fallen London Player Character: This is you, and you are magnificent.

TtH

• Time, the Healer: A weekly (or near-weekly, depending on the servers) event that does very many disparate things.

BiS

• Best in slot: An item which gives the most of a particular quality (highway stat, advanced stat, etc) when compared to all other items in its equipment category.
  • Strict BiS: the strict interpretation of best; this item is truly superlative and there are none that can compare.
  • Shared BiS: a slightly looser interpretation; there are other items as good as this one, though there are none better.

Carousel

• A repeatable loop of actions, resulting in one large payout at the end. Examples: Port Cecil (Guide), Publishing a Newspaper (Guide).

Wheel

• Similar to a carousel, except the options available at any one point are randomized either through a randomizer quality or by being cards in a deck. Examples: Professional Activities (Guide), The Maze-Garden (Guide).

Progression terminology

Quality

• An aspect of your character's identity, personality and history. All qualities have levels, though some only have one level. In the back-end of the game, even items are (discrete) qualities!

CP

• Change point: Tracks progress toward increasing the level of a quality. Could be considered experience, of a sort — see Leveling (Guide).

Pyramidal quality

• A quality that uses CPs to advance, instead of a quality that is directly incremented. It's "pyramidal" because you need 1 CP to advance to level 1, 2 CP to advance to level 2, 3 CP to advance to level 3, and so on. Compare "Discrete quality" below. Pedantically, these are more obelisk-shaped, as CP-to-next-level caps at 70 for highway stats and 50 for other qualities.

Discrete quality

• A quality that does not use CPs, such as Honoured with a Statue. Compare "Pyramidal quality" above.

Back-end/wiki terminology

QLD

• Quality level description: The name given to a particular level of a quality. For example, Scandal 1 has the QLD "Suspect".

QCD

• Quality change description: The text that appears when a quality changes. For example, "You only have one point of Cat-Like Tread left. Finish quickly or escape now!"

QVD

• Quality-variable description: Text within a storylet or card that changes depending on your character's qualities. For example, the first word of the name of the TLC is determined by your Chosen Site; the second is determined by Foundation.

slet

• Storylet.

Content & Stories

PoSI

• A Person of Some Importance: After you have made your name, you must become a PoSI to unlock most further content.

Content Cycles

Since Fallen London turned 10, FBG has operated in a system of content cycles where a particular aspect of the game is focused on. Most (though very much not all) major new content released during a cycle is part of its setting or story.

• 10th Anniversary: the conclusion of the four Ambitions, the addition of the University Laboratory, Parabolan Base-Camp, and Bone Market, and various other changes to the game. The Treasure slot was also added, featuring the items gained at the conclusion of the Ambitions. It also introduced the new stats of Glasswork, Monstrous Anatomy, A Player of Chess, Kataleptic Toxicology, Shapeling Arts, Artisan of the Red Science, and Mithridacy.
• The Railway: an extensive endgame storyline that immediately followed the anniversary and featured a new story about a rail line to Hell and the Tracklayer's Union that works on it. It added many stations along the railway that were built in sequence. In addition to adding ways to increase all main stat caps from 200 to 230, it also introduced Steward of the Discordance,and Neathproofed.
• Zeefarer was the next cycle, targeted at midgame players. It introduced Zeefaring as well as a complete overhail of zailing mechanics, many new zee ports and reworks of existing ones, upgrades for the Destiny and Ship slots, as well as new slots for Boon, Burden, and Tools of the Trade. It also featured a substantial rework of Fallen London's early and mid game. Its key story, Evolution (Guide), followed the Youthful Naturalist's investigations into death.
• Firmament: the current content cycle. Targeting endgame players, its main storyline takes place on the Roof and is yet underway. It has introduced Chthonosophy, Inerrant, and Insubstantial as well as new equipment slots for Adornment, Luggage, Airship, and Crew.
