How to Unlock Erinnyes Forest

Have Access to Fontaine

To unlock Erinnyes Forest, you must first access the Nation of Fontaine itself. The very first time you visited it, you will find yourself in Romaritime Harbor, where you can utilize the Aquabus there to visit the walled city of the Court of Fontaine.

From there, you can use the Aquabus again and ride towards the Marcotte Station thru the Navia Line, to step foot on Erinnyes Forest!

Reach Erinnyes Forest On Foot

Alternatively, once you've gotten access to Fontaine, you can visit Erinnyes Forest on foot. Since it's not a barricaded island, you can swim directly from all directions to reach it!

Activate the Statue of Seven

When you arrive at the Marcotte Station, head north-east to find the Statue of Seven; activating the statue will display the Erinnyes Forest region map, making it easier to explore.

Erinnyes Forest Areas and Notable Locations

Foggy Forest Path

A forest in the Erinnyes with a crystal-like tree in the middle and a key location in the Foggy Forest Path quest.

Weeping Willow of the Lake

A Lake with an another altar underneath the willow. The puzzle underwater can be solved during the Wilting Weeping Willow quest.

Loch Urania

A giant loch with a huge ball on the water and a huge gust of wind surrounding it. The strong winds can be removed during the Furious Mouth of the Spring World Quest!

Lumidouce Harbor

The main trading port of Fontaine that leads to other nations. This place is where you can find the sequel to the Fontaine Research Institute Chronicles quest series: An Expected Plan.

Opera Epiclese

The Opera Epiclese stands at the edge of the Island, directly north of Poisson. The Opera Epiclese is where the tribunal of the Iudex and the Hydro Archon, Furina happens, making it one of the most important places in the nation!

During the Archon Quest Chapter 4: Act 3, it was also shown that the Opera House is directly connected down to the Fortress of Meropide, governed by its Duke, Wriothesley!

Fortress of Meropide Location Guide

Marcotte Station

The Marcotte Station is the only Aquabus line that directly connects the Court of Fontaine to Erinnyes Forest, making it a vital transportation route for all citizens of Fontaine. From the Court Region Waterway Hub, use the Navia Line to reach Marcotte Station!

Fountain of Lucine

Another point of interest in Erinnyes Forest is the Fountain of Lucine. Where the most mundane citizens throw Mora into, for it to grant their wishes. Yet, for the more privileged and more learned populace, they use Hydro Sigils instead, in exchange of awesome goodies!
