Supremacy Overview and Explanation

Intent of Supremacies
The intent of supremacies is to be a large scale storylet that encompasses multiple players from various regions of Sunless Sea. Each faction is at odds with one another and requires your direct assistance to gain dominance. There are a few stories that will inadvertently further a faction's goals (and thus increase their supremacy), but these occurrences are rare.

Supremacy levels are listed in the player's journal, but they use a descriptor rather than a numerical value, so you will have to look at the individual Supremacy pages to try and figure out how far along you actually are (they are linked below for your convenience). When a faction's Supremacy value reaches 7, a faction has claimed dominance and the overarching story comes to a conclusion when the player next returns to London. You cannot undo the effects of the London event, so make sure you ally with the faction you want to have control.

WARNING : There are dire consequences for raising a non-London supremacy to its maximum. Namely, the primary benefactor of the game, The Dark-Spectacled Admiral in London will no longer be available. That means you will no longer be able to hand in port reports or be sent on missions to collect Strategic Information. The game fails to mention this.

The Factions
There are currently four factions all vying for dominance in Sunless Sea. Each of them has radically different ideals and goals.
 * SS wolfstackdocks portsmall.pngmacy: London : This supremacy represents the current regime of London. London's goals aren't altogether clear other than to establish rule of law over islands in Sunless Sea.
 * : This supremacy represents those who support the goals of an artificial god, the Dawn Machine. At one point, this faction was part of the London admiralty, but splintered after the machine gained self awareness.
 * SS khansheart_portsmall.pngmacy: The Khanate : This supremacy represents the people of the fourth city, Karakorum, referred to as the Khans. The Khaganian faction is devoted to preserving their culture and way of life and resents change or influence from the outside world.
 * SS ironrepublicsmall.pngmacy: The Anarchists : This supremacy represents the faction of devils and revolutionaries who are unhappy with those in control of London. The long term goal of the anarchists is not well explained in Sunless Sea other than seeking to oust those in current possession of power.

Raising and Lowering Supremacy
Raising a supremacy value is considerably more common than lowering one. Keep this in mind because as I mentioned at the top, there are a few events that will raise faction dominance that might not be intonated in your choices.

Primary Means of Increasing Supremacies

 * SS surmisesmall.png Intelligence : This is the primary means of raising the London, The Khanate and Dawn Machine supremacies. The Anarchists require something different.
 * Obtaining: There are two primary means for obtaining this item:
 * 1. Combine 2x SS wilmotsendsmall.pngegic Information in your inventory by right clicking the item and selecting combine.
 * 2. Extract the information from a network by means of the Seek Intelligence event. The current locations for extraction are either SS_Locations_Port_Carnelian.png Port Carnelian or SS Locations Khan's Heart.png Khan's Heart.
 * Use: Turning this item in at the following places and to the following people:
 * 1. SS Characters The Dark-Spectacled Admiral.png Dark-Spectacled Admiral in London for the London faction. Note: This will not always increase Supremacy: London, it is a chance on turn in.
 * 2. SS voraciousdiplomatgaz.png The Voracious Diplomat in London for the Dawn Machine faction. Note: This will not always increase Supremacy: The Dawn Machine, it is a chance on turn in.
 * 3. Selecting the Influence Affairs in Port Carnelian or Decide Port Carnelian's fate event in Port Carnelian will allow you to hand over a Vital Intelligence for supremacy of a faction of your choice. This is the primary way to increase Supremacy: The Khanate


 * SS mechanism2small.pngies for the Work : This is the primary means of increasing Supremacy: The Anarchists.
 * Obtaining: The player must travel to the surface city of SS liberationofnightgaz.png Vienna and side with the Fidgeting Agitator through the "Psst! Friend! Strike a blow for freedom, will you?" and Another favour for the Agitator events.
 * Use : Deliver the supplies to London and select the Deliver Supplies for the Work event.


 * SS mementomorismall.pngto Mori : You can only get one of these per game unless you pass one down using a legacy, but you can donate this to a faction of your choice for a large gain in supremacy.
 * Obtaining: Complete the Irrepressible Cannoneer's storyline.
 * Use : 
 * 1. Give it to the Dark-Spectacled Admiral in London
 * 2. Give it to the New Sequence (aka Dawn Machine) in the Grand Geode
 * 3. Give it to the Khanate in Khan's Glory
 * 4. Give it to the Anarchists (aka Calendar Council) in the Iron Republic

Primary Means of Decreasing Supremacies

 * The Influence Affairs in Port Carnelian will allow you to decrease either London or Khan supremacies.
 * The "Report the Fidgeting Agitator to the authorities" action in Vienna decreases Anarchists' Supremacy by 2 (can it be done multiple times?)
 * I don't think there is currently a means to decrease the Dawn Machine supremacy.
