The Heir of Memories is the first quest in the series of The Fate of Atlantis in Assassin’s Creed Odyssey.
Your task is to meet the contact in a small island to find out what this is about.
Here’s a walkthrough of The Heir of Memories in AC Odyssey.
This quest is recommended for those level 52 and above, but it differs according to your own level.
Meet the contact
Your main objective in this quest is to meet the contact. In order to do so, you need to get to the small island with the Poseidon statue.
It’s right below Chios (east of the map). The exact location is shown in the map below.
The fastest way to get there is to probably fast travel to Chios and summon the Adrestia.
Sail to the island.
Get to the bottom of the statue and you will meet Aletheia, the contact.
Aletheia is apparently one of the first men, i.e. the Isu.
During the conversation, I chose to pledge to hold the staff.
After pledging, you will be transported back to Layla.
Get to the wall
As Layla, you will hear Aletheia’s voice. Just listen to the conversation first.
Next, you have to get to the wall or door on the right side.
When you get there, a cutscene will load by itself. All you have to do is to watch the conversation.
You now have to find some symbols to open the door. In order to do so, you need to get back to using Alexios or Kassandra and you will unlock three new quests.
The current quest completes here and you will earn some drachmae.
