All Fontaine World Quests Location & Guide in Version 4.2

Archon Quest Act V (Masquerade of the Guilty)

➥ The last Archon Quest for Fontaine! Just check your quest navigation and you can start it, that is if you already completed the previous Act first.

Search in the Algae Sea (In the Wake of Narcissus)

➥ This quest chain is the last and the closing part of the whole Narzissenkreuz Ordo questline. You’re going to uncover the truth behind the identity of Mary-Ann and the history of Narzissenkreuz Ordo (not me skipping everything).
➥ You can get this quest on your quest navigation tab automatically after completing Unfinished Comedy. It will start in The Narzissenkreuz Ordo.

The Wild Fairy of Erinnyes

➥ In this quest, you will help a mysterious Melusine called Pahsiv to cleanse the filth around the new Fontaine area. By the end, you will unlock a small underwater area under Marcotte Station – Weeping Willow of the Lake. There are 2 Hydroculus in that area so you might want to complete this quest asap~
➥ Teleport to Marcotte Station’s S7 and you should notice the quest icon on the map. Go to the fountain with the lion statue and interact with the Carved Stone Tablet to start the quest.

Questioning Melusine and Answering Machine

➥ In this quest, you need to help a Melusine find a ‘killer’ and run around the new areas searching for clues. By the end, you will unlock a small underwater room/base near the S7 in Morte Region. This one is pretty short if you know what you’re doing and skip the whole dialogue (it’s pretty sadge).
➥ You can start the quest by getting near The Steambird (Fontaine Reputation NPC) in the Court of Fontaine. You will see a Melusine arguing with a male NPC there.

Free Verse

➥ In this quest, you will have the ability to talk to a cat and dog, fulfilling their wishes so you can be friends with Penny; a lonely girl. The quest itself is not that long.
➥ Teleport to the waypoint southeast of Opera Epiclese and head to the shore (towards the waverider waypoint) and you will see the quest icon on top of a little girl.

Wish-Fulfilling Treasure Hunt

➥ You can only start this quest after completing a sub-quest in Narcissus’ Traces where the Tower of Gestalt goes underwater and disappears from the surface map. By completing this quest, you will also get the long-awaited Enigmatic Page (X).

Impromptu Poem of the Crimson Dawn

➥ This quest can be started whenever. But it’s best if you complete the Free Verse quest first because it’s kinda related to it, just a little bit. Both these quests are short anyway.
➥ Teleport to Weeping Willow of the Lake southeast waypoint and head north to the small shacks with two cages at the front. Interact with the guy inside the cage to start the quest.

Through the Looking Glass (Happy Birthday)

➥ In this quest, you need to interact with 6 paintings in underwater ruins (you have already gone to all of them if you already completed the Search in the Algae Sea quest series) and complete each puzzle to start the quest.
➥ In a way, this quest is like a closure to Caterpillar’s story since he’s involved in this one so it’s best if you complete the Search in the Algae Sea first. Refer to the image above for the location of all 6 paintings.
