How to Get to Fontaine

Finish Prologue: Act 3 First to Unlock Fontaine

The teleport waypoint by the Aquabus unlocks automatically once you've completed The Song of the Dragon and Freedom. It's the minimum requirement for unlocking Fontaine.

The Song of the Dragon and Freedom Guide

Take the Aquabus to Get to Fontaine

After updating to Version 4.0, you can get to the city of Fontaine by boarding the Aquabus in Romaritime Harbor. The aquabus' closest teleport waypoint is located near the border of Fontaine and Sumeru, and should automatically unlock once you've finished Prologue: Act 3.

How to Get to Fontaine's Aquabus

Teleport to the waypoint in the middle of Fontaine and Sumeru, summon your Waverider, and head to Romaritime Harbor. Ride the lift to the upper level and look for the aquabus.

Talking to the Aeval the Melusine will start your journey to Fontaine's main city!

What to Do if the Aquabus is Missing

If your Aquabus is missing, just interact with the nearby bench and "wait for the aquabus". The Aquabus should come back after the loading screen!

Fontaine's Unique Features

Diving and Underwater Mechanic

Because of Fontaine's Blessing, Transoceanic Sourcewater, you can explore the underwater areas of Fontaine through the Diving Mechanic!

Other than allowing you to dive into Fontaine's waters, this blessing also allows you to gain the abilities of Xenochromatic Creatures!

Diving Mechanic in Fontaine

Pneumosia Energy and Indemnitium

Pneumosia Energy is comprised of both Pneuma and Ousia—two opposing energies utilized by residents of Fontaine as a source of sustainable energy called Indemnitium, to power up the nation, and all the Clockwork Meka!

Fusing these two energies together creates a Balanced energy that activates certain mechanisms in Fontaine—or "Annihilate" machine beings.

What are Pneuma and Ousia?

Arkhe System

The Arkhe System refers to the inherent Pneumosia alignment of characters from Fontaine. This can help them interact with the Pneumosia Energy all over Fontaine and is separate from each Fontainian character's Vision!

Clockwork Meka

Clockwork Meka Previews

Clockwork Meka are machine beings that are primarily powered by Pneuma-Ousia Annihilation Reaction energy blocks invented by Alain Guillotin, founder of the Fontaine Research Institute.

These machine beings perform a number of functions, such as patrolling, defense, underwater exploration, among others. Be careful though, as not all Clockwork Meka are friendly!

Can Clockwork Mekas Operate Outside Fontaine?

Clockwork Mekas can still function even outside Fontaine, but can only do so through pre-prepared energy blocks that contain Pneumosia Energy!

Clockwork Meka Enemy Guide

Melusines

Melusines are a race of beings characterized by their long and protruding ears, and whose place of residence is primarily in Beryl Region.

From the Ancient Colors World Quest, it was also revealed that their progenitor is Elynas, a felled-dragon whose blood had polluted the rivers of Fontaine for years!

Who are the Melusines?

Fountain of Lucine

The Fountain of Lucine serves as the reward system in Fontaine where you can exchange collected Hydro Sigils with valuable items!

This system can be unlocked as soon as you reach Fontaine, but we recommend progressing through the region's Archon Quest: Act 1 for a better experience as it will point you to the fountain's location!

How to Unlock Fountain of Lucine

Fontaine Aquabus

Aquabuses are vehicles that you use to traverse the waterways that connect the Court of Fontaine and to other areas such as the Romaritime Harbor, Fountain of Lucine, and Opera Eclese.
