== Overview ==

Hearths are the heart of the settlement.  Every settlement starts with an [[#Hearth Types | Ancient Hearth]] and can construct other [[#Hearth Types | Small Hearths]] from the '''City Buildings''' menu. Hearths are [[building]]s with {{sl|Warmth}} Specialization that employ a single [[#Firekeeper bonus | Firekeeper]] to keep the Hearth lit by burning [[#Fuel | fuel]]. Fuel can also be [[#Sacrificing | Sacrificed]] in the Ancient Hearth. Every [[villager]] takes their [[breaks]] at the nearest Hearth to warm themselves, eat, and fulfill their needs. By [[#Hearth upgrades | upgrading]] the Hearth with decorations, [[housing]], and Service [[buildings]], you can unlock up to 3 tiers of stackable benefits. The Ancient Hearth can get [[#Corruption | corrupted]] at Veteran [[Difficulty]] and higher.

== Hearth Types ==

; Ancient Hearths :
<blockquote>
The heart of the colony is protected by the Holy Flame.  [[Villagers]] gather here to rest, eat, and receive clothing.  If the fire goes out, people will lose hope. '''No Hope''' [[Resolve]] effect: -20 Resolve.
</blockquote>

; Small Hearths :
<blockquote>
Small Hearths cannot be built too close to the Ancient Hearth or to each other - the ranges of your Hearths (approx. radius of 9 squares) may never overlap.

Small Hearths are identical to Ancient Hearths, except you do not receive a [[#Firekeeper bonus | Firekeeper bonus]] and you cannot [[#Sacrificing | Sacrifice]] fuel.  It is OK if Small Hearths go out, but [[villagers]] will be unable to rest or fulfill their needs at an unlit Hearth and will instead travel to the nearest available lit Hearth.
</blockquote>

== Fuel ==
[[File:Allowed fuel.png|right|300px]]
There are 4 fuels that can be burned in Hearths: {{rl|Coal}}, {{rl|Sea Marrow}}, {{rl|Oil}}, and {{rl|Wood}}. Each Hearth you have in the settlement consumes fuel.

You can decide which type of fuel will be burned in each Hearth using the checkboxes next to the fuel types in the ''Allowed Fuel'' menu. All Hearths share this setting. If you have multiple fuels selected, the leftmost one will always burn first. There are also options in the settings that allow you to customize which fuels are automatically enabled when starting a new settlement.

== Firekeeper bonus ==

Every settlement starts with an [[#Hearth Types | Ancient Hearth]] which must '''always''' remain lit.  If the fire goes out, all [[villagers]] will lose 20 [[Resolve]]. To keep the flame burning, a Firekeeper and a steady supply of [[#Fuel | fuel]] is needed. Your choice of Firekeeper in the Ancient Hearth will grant your settlement a species-specific bonus. Small Hearth Firekeepers don't provide any bonuses.

== Villager Breaks ==
: ''Main article: [[Breaks]]''

Every few minutes [[villagers]] have to return to a nearby [[Hearth]] for a break, to eat, rest, and satisfy needs. All consumption happens during breaks. [[Villagers]] of different species take breaks at different Intervals.

== Hearth upgrades ==
[[File:HearthUpgradeRequirements.png|thumb|right|360px|Decorations Needed]]
Level 1 Hearth upgrade is available from the start. Upgrading to level 2 and 3 requires you to [[unlock]] levels 2 and 4 of the '''Brass Forge''' respectively. 

Click on the Hearth to see what is required to upgrade. As seen on the image on the right in the ''Upgrade Requirements'' section, we still need 4 <span style="color: {{PerkGreen}}">Comfort</span> Decorations and 4 <span style="color: {{PerkBlue}}">Aesthetics</span> Decorations before the Hearth upgrades to level 2.

* [[Housing]], Decorations, and Service [[buildings]] need to be placed fully within the Hearth Radius for them to count towards upgrades.
* The Hearth upgrades itself automatically once all the requirements are fulfilled.
* Both Ancient and Small [[#Hearth Types | Hearths]] can be upgraded.

== Sacrificing ==
[[File:Sac menu.png|right|300px]]
[[File:Sac hearth aura.png|thumb|right|250px|Sacrificing aura]]
[[#Fuel | Fuel]] can be sacrificed in [[#Hearth Types | Ancient Hearths]] to temporarily gain powerful positive effects. Sacrificing is extremely resource intensive and requires significant labor investment, or even restructuring of the whole settlement, should you wish you keep it up for an extended period.

You can Sacrifice up to 3 stacks of {{rl|Wood}}, {{rl|Coal}}, {{rl|Sea Marrow}}, or {{rl|Oil}}. Each fuel's Sacrificing stacks are independent. To choose how many stacks you want to Sacrifice, use the green arrows next to the fuel type. Activating Sacrifice immediately consumes 1 unit of fuel, even if you are paused. If you only have 1 unit of this fuel to begin with, you will keep the effect for as long as you are paused. If you don't have any fuel of one type, its green arrow is going to appear grayed out. Do not forget to reset the stacks to 0 once the need for Sacrifice has passed - you will quickly run out of fuel otherwise. There's also a checkbox to ''Stop after storm''.

There are 3 visual indicators of Sacrificing taking place:
* An orange aura around the [[#Hearth Types | Ancient Hearth]].
* A [[Perk]] in a gray outline with the number of stacks in the Perk section on the bottom left of the screen.
* An exclamation mark in a yellow diamond next to the fuel [[Resource]] Category in the upper section of the UI. It says "You are sacrificing fuel in the Hearth." if you hover over it.

Each fuel type grants different boons:
{| class="wikitable" 
|+ Sacrifice effects
|-
! style="font-weight:bold;" | Fuel
! style="font-weight:bold;" | x1 Stack
! style="font-weight:bold;" | x2 Stacks

| +75% [[Glade Event]] working speed
|-
| {{rl|Oil}}
| +25% global production speed
| +50% global production speed
| +75% global production speed
|}

There are 2 modifiers that affect Sacrificing efficiency, outside of [[Cornerstones]]: 
* '''Sacrificial Flame''': resources sacrificed in the Ancient Hearth burn 10% longer. A '''Monastery of the Vigilant Flame''' level 7 [[upgrade]].
* [[Prestige]] 18: the Ancient Hearth seems to have a defect. No matter how hard the firekeeper tries, sacrificed resources are burning 35% quicker.

The table below shows how much fuel you need to Sacrifice per stack to keep the effects, depending on your [[upgrades]] and [[Difficulty]]:

== Corruption ==
[[File:hearthcorruption.png|thumb|300px|Corruption bar in the Ancient Hearth]]
: ''See also: [[Blightrot]]''

Blightrot infects Hearths. The more [[Blightrot Cysts]] a Viceroy generates from [[Rain Engine]] use or [[Glade Events]], the faster their Hearths get corrupted during [[Storm Season]], when Blightrot Cysts open up. Once the [[#Hearth Types | Ancient Hearth]] reaches the Corruption limit, it triggers '''Voice of the Sealed Ones'''. Voice of the Sealed Ones sends out 3 ghosts from the Ancient Hearth that seek out and kill 3 random [[villagers]]. As soon as the Hearth discharges, Corruption is reset to 0 and starts rising again. 

=== Lowering Corruption ===
The only way to lower Corruption during Storm is to employ the help of [[Blightfigher]]s in a [[Blight Post]]. Blightfighters search for Cysts and burn them with {{rl|Purging Fire}}. '''Every Cyst burned lowers Corruption by 50'''. Once all Cysts have been burned, any new ones will not open up till next Storm Season. Any Cysts left close and Corruption resets to 0 as soon as the year ticks over and Drizzle Season starts.

=== Corruption Resistance and Corruption rate ===
'''Corruption Resistance''' or Hearth Resistance is a measure of how high the Corruption limit is. The higher the Corruption Resistance, the more time it will take for '''Voice of the Sealed Ones''' to activate. An [[#Hearth Types | Ancient Hearth]] that hasn't been [[#Hearth upgrades | upgraded]] has 1000 Corruption Resistance. Every Ancient and Small Hearth [[#Hearth_Upgrades|level]] raises Corruption Resistance by 150. It can also be raised with different [[Effects]].

The Corruption rate per Cyst is 60 Corruption/minute up to [[Prestige]] 10, and 90 Corruption/minute from Prestige 11 onwards. 

Assuming a Hearth upgraded to level 2, you will reach the Corruption limit of 1300 at least once without burning any Cysts:
* At 60 Corruption/minute in a 2-minute Storm with 11 Cysts.
* At 60 Corruption/minute in a 4-minute Storm with 6 Cysts.
* At 90 Corruption/minute in a 4-minute Storm with 4 Cysts.

== Hearth Tips ==

* Use {{Species link|Beavers}} as Hearthkeepers when you are running low on fuel and {{rl|Wood}}, especially on [[Marshlands]] and the [[Sealed Forest]].
* {{Species link|Harpies}} are nifty as Hearthkeepers before and after [[Glade Events]] to carry goods to and from these Events.
* {{Species link|Foxes}} are excellent during the [[Storm Season]] as Hearthkeepers to keep [[Hostility]] down and stop [[Forest Mysteries]] from triggering.
* {{Species link|Humans}} are invaluable when playing [[World Map#World_modifiers|World Modifiers]] like '''Land of Greed''' to slow down the Queen's [[Impatience]].
* {{Species link|Lizards}} as Hearthkeepers will help you in achieving [[Resolve]] - based Orders.
* Since Firekeepers in [[#Hearth Types | Small Hearths]] don't offer a species-specific bonus like they do in the [[#Hearth Types | Ancient Hearth]], you can take advantage of its {{sl|Warmth}} specialization synergy with Lizards.
