Fontaine

Fontaine is one of the seven regions of Teyvat. It is the nation that worshipped Focalors, the Hydro Archon and God of Justice.
Archon Quest Chapter IV takes place in this region.
==How to Access==
Access to Fontaine is unlocked after completing the . Teleport Waypoints in Realm of Farakhkert, Sumeru and Marcotte Station, Fontaine are also unlocked after completing the .
==Description==
Of the regions of Teyvat, Fontaine prides itself as the hub of culture and the arts; or in the words of Francis, a traveling merchant from the region, "true beauty and elegance." The newspaper The Steambird is the main newspaper of the Court of Fontaine; Mona is a columnist on it, suggesting that they have writers from all across Teyvat. According to the Steambird, Fontaine is located in the center of TeyvatHoYoLAB: The Steambird Special Edition I: The Terrestrial Sea, Origin of All Waters and is the source of all waters on the continent. Its entire continental plate is elevated, making it significantly higher than other nations. At the edge of Fontaine is a massive waterfall that stretches for thousands of meters.
Fontaine boasts its immersion in the development of technology, as referenced in multiple story points — such as the Mikage Furnace, designed by Fontaine engineers, including Xavier; and limited events — such as in Fabulous Fungus Frenzy, where the Wisdom Orb is a Fontaine-local-designed equipment designed to suppress specific behaviors in organisms.
Minor events that have featured Fontaine's technologic prowess include Core of the Apparatus, which features Fontainian inventions that can manufacture toys and furnishings, and Evermotion Mechanical Painting, which features mechanical gear systems.
There is a special energy system in Fontaine; however, it is mentioned to be on the verge of declining, causing many people to seek alternative sources. Additionally, Santon states that the air in Fontaine is "practically toxic fumes" and that there is much less connection to nature there, though he is not necessarily referring to the entire region.
According to Vasco, a diving certificate can be obtained in Fontaine, and diving itself is an important profession in the nation.
Liben had described Fontaine's locals as believing that some type of "judgment" was "soon to come," possibly in reference to the prophecy described in the Archon Quests about the nation being destroyed by rising sea levels to absolve its people of their "sin."
The Fontaine Research Institute is located in Fontaine, though its original main buildings were destroyed in an experiment conducted by Edwin Eastinghouse.
Other races also reside in Fontaine, such as the Melusine and, once upon a time, the Oceanids.

==Notable Features==
Fontaine features many unique mechanics and environmental hazards:
===Arkhe===
Arkhe is composed of two opposing energy types: and . When they meet, an annihilation reaction will be triggered. A character that possesses an Arkhe alignment can trigger a reaction by performing a Normal, Charged, or Plunging Attack on an object with the opposite alignment.
There are various ways that a character can gain an Arkhe alignment:
* Fontanian characters all have an innate Arkhe alignment.
* Furina can switch her Arkhe alignment by performing a Charged Attack.
* The Traveler has alignment while resonated with .
* The Sword of Narzissenkreuz grants an Arkhe alignment while it is equipped. This alignment can be switched at the "Little Fountain" in Annapausis.
* Characters can receive a temporary Arkhe alignment by picking up a Pneumousia Block. This temporary alignment expires after a short time, or when an Arkhe reaction is triggered.
Arkhe reactions can cause the following effects:
* Temporarily shutting down 
* Stopping an Enhanced Pneumousia Amplifier from applying buffs to nearby enemies
* Launching The Miraculous Antoine Roger Aircraft, which will typically grant a Remarkable Chest upon reaching its destination after dealing with any obstacles
* Balancing a Pneumousia Relay, which can trigger various effects
* Opening a Pneumousia Storage Box
===Diving===
Unlocking the first Statue of the Seven in Fontaine grants the Diving ability. Rather than only being able to swim along the surface of the water, players can also dive and explore below the surface. This applies to all swimmable bodies of water in Fontaine except the sea around Petrichor.
* While in any body of water which permits diving, the player will not consume Stamina and cannot drown. Fast swimming consumes Aquatic Stamina instead, and when it depletes the player must slow down, similar to how sprinting works on land.
* Normal Attacks, Elemental Skills, and Elemental Bursts are disabled while in the water. Instead, the player has a weak "water string" attack that does a small amount of damage to enemies. However, this attack can be used on Xenochromatic Creatures to acquire various abilities from them (see Xenochromatic Abilities below).
* Allogravity-Condensed Water Bodies are floating cubes of water found at the site of the Fontaine Research Institute explosion. The player can dive inside them just like most other bodies of water in Fontaine.
** The player receives an on-screen warning if they approach the side or bottom boundaries of the cube; continuing and crossing said boundary will cause the player to start falling.
** During the , several of the cubes are contaminated by condensing components from the exploded Arkhium reactor. These cubes have a purple tint and the player diving inside them will continuously accumulate Turbulent Energy Flow until the condensing component is found and removed. Accumulating too much Turbulent Energy Flow causes all characters to drown.
* Entering a Current will cause the player to move quickly along a pre-determined path, only able to control movement laterally within it.
* Hidden underwater locations and objects can be revealed by touching an Echoing Conch or using the Sonar Waves Xenochromatic ability.
* Huge Shells contain objects which are revealed when struck.
* The player can recover HP by touching a Recovery Orb.
===Energy Storage Devices===
Energy storage devices can be used to power machines.
* The Fixed Storage Device is locked in place, while the Energy Transfer Device can be picked up and deployed near an object to be powered.
* These devices are red when uncharged and blue/green when charged.
* Some machines require power from a charged energy storage device to function:
** Boxing Dummies (unofficial name) must be attacked to trigger an effect.
** An Energy Transfer Terminal can be used to extract energy from one device and transfer it to another. The player may need to switch to another terminal (by pointing at it with the viewfinder) to be able to see the target object. These terminals are also used to read Cipher Letters and occasionally operate other machines.
** Stabilizers require the player to attack it while its indicator is within a blue zone three times to trigger an effect.
* Flying Energy Thieves are glowing balls found in the Geode Mine Shaft that disable a storage device carried by the player.
===The Symphony===
Available only in the Nostoi Region, the Symphony is a game mechanic where the player can cause objects with musical note icons above them to stop or start moving.
* Mysterious Bookshelves are doorways in the Faded Castle. To open one, the player uses the Symphony to halt a Mysterious Grimoire, capture it, deliver it to the Bookshelf, then use the Symphony to move the books out of the way.
* The Ancient Autoharmonic Music Box is powered by the Symphony. The player can find scores and play them on the Music Box to unlock rewards and reveal the history of Remuria.
* Auric Anglerfish are large mechanical fish, each of which holds a chest in its mouth. Using the Symphony to pause one while near its tail will cause it to stop and hold its mouth open for a brief time, allowing the player to collect the chest.
* Autoharmonic Reed Pipes are devices which can be calibrated to one of three different notes with the Symphony. They are always found in groups, and the puzzle is solved when all Reed Pipes at a location are set correctly.
* The Faded Castle contains a stage that hosts a special challenge that will test the player's skills with the Symphony.
* Scylla looks like a whale, but he is a powerful Vishap that lives in the waters of the Sea of Bygone Eras. He is initially bound by Dragonborn-Suppressing Shackles, which the player must release by solving Symphony-based puzzles. Once he is free, Scylla is usually within sight of the player while swimming in the Sea, and tapping a button will cause the player to be rapidly drawn to him. While next to Scylla, the same action will allow the player to be quickly propelled in any direction away from him.
* Certain special coral formations contain Swaying Eels; the player can interact with a formation to get the Eels to pop in and out. Use the Symphony to pause them when they are all out to solve the puzzle.
* Washer Octopi respond to the Symphony, which can be used to manipulate them in various ways. Resonant Anemones light up when a Washer Octopus is nearby. Lighting up all the Anemones in a location simultaneously will trigger an effect.
===Xenochromatic Abilities===
Special abilities can be obtained from Xenochromatic Creatures found underwater. A button will appear which allows the player to use the ability; hold it down to aim it.
* The ability grants a shield and the ability to fire damaging shockwaves. Absorbing an attack with the shield aiming will increase the shockwave damage. This is the only way to defeat Bullet Barnacles, and is useful for blocking High-Pressure Water Vents to position Fantastical Floating Balls in their corresponding rings.
* The allows the player to fire an energy beam which can damage enemies and manipulate certain objects. Unlike the other abilities, it can also be obtained and used on land by interacting with certain ecological research devices. The ability is particularly useful for:
** Destroying the floating objects over Contaminated Bacterial Mats to remove them
** Moving or merging Dew Bubbles, used to trigger Harmonious Reed Pipes
** Spinning Floating Crystal Flowers, causing Floating Crystal Platforms to appear
** Moving Humongous Hat Jellyfish, which can be used to launch the player into the air
** Manipulating Operable Mechanisms to commandeer Dangerous Autocannons, redirect Energy Flows, and solve other puzzles
** Launching Potential Energy Orbs into their targets when standing within a nearby golden sign
* The grants the ability to release waves of sonar that can detect significant objects as well as damage enemies.
* The grants the ability to fire Fontemer Water Blades. As well as attacking enemies, it's also useful for cutting the glowing spots on Fontemer Seagrass. Cut all the spots within a short time to release whatever is trapped by the seagrass.
* The grants the ability to throw a Bing-Bang Hat Bomb and remotely detonate it. This ability is particularly useful for destroying underwater rock piles, Red Meanies, and Strange Eels. The latter two, when found in groups, must be all destroyed within moments of each other or they will respawn.
===Other===
* A Beastly Rift is a challenge where the player must defeat waves of while protecting several crystals.
* Elynas Prisms (unofficial name) can be attacked to send an energy projection in the direction of the attack. Some Prisms can be moved, and some are inactive until struck by energy from another Prism. Some Prisms are covered with stone and must be struck by energy from another prism to remove the stone and trigger an effect.
* Experimental Focusing Mirrors are encountered during the . Each one can be used to relay a beam of light to eventually activate a device in the center of the ruins where they are found.
* can be offered at Statues of the Seven in Fontaine for rewards.
* Collecting three Hydrograna will create a Hydro Core that continuously applies within an Area of Effect around the player for a short time. The effect can also be triggered with fewer Hydrograna by self-applying .
* Jadewater Fruit are objects that can be damaged and eventually destroyed with Elemental Reactions, releasing whatever is inside (usually a Chest, a Mora Chest, or an Enemy).
* Looking Glasses can teleport the player to and from certain locations in ???. Only the ones which glow purple are active and can teleport the player.
* Optical Couplers are found in the Tower of Ipsissimus. During , the player must rotate devices in the center of each room to align the couplers in order to proceed.
* A Water Volume Detection Crystal can be activated by continually applying to it, triggering various effects.

==Trivia==
* In the trailer Teyvat Chapter Storyline Preview: Travail, under the title of the quest Masquerade of the Guilty, there is a line written in Teyvat's Latin script. It reads "Iustitia omnia vincit" which roughly means "Justice conquers all," and is modified from the Latin phrase .

* The Kamera comes from Fontaine, as told by Xu when giving the Snapshots World Quest.
* Midori claims that Fontaine has an "air-rail" system that allows citizens to travel along the sky, as Ramsay wrote in his diary. However, there is no substantial evidence of this, and in the World Quest International Travel Log, the player finds out that most of what Ramsay writes in his diary is fictional.
* Rock 'n' roll originates from Fontaine.
* All Oceanids are from Fontaine. They are loyal to the previous Hydro Archon, Egeria, and allegedly left their native region because of the ideals of the new Hydro Archon, Focalors.
* In Vol. 2 of Heart of Clear Springs, Fontaine is described as "sapphire-blue."
* Fontaine is currently the only nation that does not have any One-Time Domains.
* After Focalors' execution by the Oratrice Mecanique d'Analyse Cardinale and the destruction of the Hydro Archon's divine throne, Fontaine is currently the only region without an Archon, with the duties related to the Hydro Archon being instead passed to Neuvillette, the Hydro Dragon Sovereign.
** This also makes Fontaine to be the first nation ruled by a Dragon Sovereign.
===Etymology===
* means "fountain" in French, which is fitting for the home of the Hydro Archon.
* The Chinese name for Fontaine, , may be a clipping of "Fontainebleau" (), a commune in the metropolitan area of Paris known for its castle sitting right by the water.
