The Gates of Atlantis Guide – Assassin’s Creed Odyssey

As you progress through the main story of Assassin’s Creed Odyssey, you will arrive in the mythological city of Atlantis. In Atlantis you meet your (real) father and he tells you he needs your help. Basically there are 4 artifacts throughout Greece that must be returned to him to seal Atlantis. This guide will show your the locations of the 4 artifacts as well as tell you how to complete The Gates of Atlantis quest. Let’s get started.

The Gates of Atlantis Quest Objectives

To complete The Gates of Atlantis quest line, you will need to complete a number of objectives. Once you’ve returned all 4 missing artifacts, you will be shown a game ending. The objectives you need to complete are:

• Return the Artifacts to Atlantis.
• One Artifact is in Boeotia (Sphinx).
• One Artifact is in Kythera (Cyclops).
• One Artifact is in Lesbos (Medusa).
• One Artifact is in Messara (Minotaur).
• Seal Atlantis.

Keep in mind that Medusa is a level 50 boss fight, so this is basically an end game side quest. Be geared accordingly.

Where is the Artifact in Boeotia?

Each artifact you are sent to collect is guarded by a mythical creature. The first artifact, located in Boeotia, is guarded by a Sphinx. Unlike the other 3 artifacts on this list, this artifact is acquired by answering riddles the Sphinx asks you. Before you can do this though, you need to first complete the following quests:

Boeotia Artifact Quests

• Lore of the Sphinx (Boeotia).
• Awaken the Myth (Boeotia).

At the end of the Awaken the Myth mission, you will arrive come face to face with the Sphinx. At this point will need to solve 3 riddles to get the artifact it is guarding.

Where is the Artifact in Kythera?

The artifact in Kythera is guarded by a Cyclops. This Cyclops will need to be killed to gain the artifact it is guarding, so be ready for a boss fight. Before you are able to face off against the Cyclop, you need to complete a number of side quests on Kythera Island. The quests you need to complete are:

Kythera Artifact Quests

• A God Among Men (Kythera Island).
• Left to Dye (Kythera Island).
• Stairway to Olympos (Kythera then Forgotten Isle).

When you reach the Stairway to Olympos side quest, the character of Empedokles will tell you to meet him on the Forgotten Isle. After you reach the Forgotten Isle you must journey deeper inside to reach the Cyclops. When the Cyclops is killed, you will receive its artifact.

The Lesbos artifact is probably the hardest of the 4 to get as it involves completing a number of quests as well as defeating a level 50 Medusa at the end. With that said, here are the quests you will need to complete in order to get the artifact from Medusa on Lesbos:

Lesbos Artifact Quests

• Romancing the Stone Garden (Lesbos).
• Love’s Long Shadow (Lesbos).
• Hard to Artemis (Chios).
• Heavy is the Spear (Lesbos).
• Keys to Happiness (Lesbos).
• Writhing Dead (Lesbos).

When you complete all of these quests, you will be taken to the Petrified Temple. Inside the Petrified Temple you will face off against Medusa. For killing the Medusa you will unlock one of the artifacts you need to seal Atlantis.

Where is the Artifact in Messara?

The final artifact can be located in Messara. This artifact is being guarded by a Minotaur. Luckily for us, getting to the artifact is a lot less of a journey than the previous artifact we collected. Like every other artifact before, you will need to complete a number of side quests before reaching the boss fight. The side quests you need to complete are:

Messara Artifact Quests

• Myths and Minotaurs (Messara).
• Of Minotaurs and Men (Messara).
• He Waits (Messara).

Once you’ve gotten to the end of the He Waits quest, you will enter a Labyrinth. At the end of the Labyrinth is the Minotaur. Defeating the Minotaur will earn you another artifact needed to seal Atlantis.

The Gates of Atlantis

Once you’ve collected all 4 artifacts listed above, make your way back to Atlantis. Take all 4 artifacts and place them in the 4 pillars around Pythagoras. Once all 4 artifacts are in their rightful sockets you will get a bunch of lore dumped on you from a Alethia. Once Alethia is done talking speak with Pythagoras for more lore. Pythagoras will tell you that he can’t seal Atlantis. After some arguing, you eventually convince Pythagoras to seal Atlantis off. To do this walk up to the console. This will trigger a present day sequence.

In the present day, go up to the same console to trigger a cutscene. During the cutscene you learn there is a beam of light missing. You need to fix this. Climb the right wall into the opening. Go into the opening to find three mirrors. Turn the mirrors so they match the screenshot above. This will send light to the room. Go back to the room with the globe to trigger another cutscene. Completing this story arc unlocks this ending below (via Dan Allen Gaming).
