Passage of the quest "Memory’s Final Chapter"

How to start a task

Before you can take on this mission, you will need to complete a number of other quests related to the final of the corresponding chain, namely:

• world quest "Aranakin’s Old Friend" .
• world quest "Aranaga’s Memory" .
• world quest "Aragaru’s Drawing" .
• You may also need to complete the quest "Hello, thank you and goodbye" .

Once all three tasks are completed, a new mission will automatically appear in your journal. Next, you will need to go to the Mawtiyima Forest and chat there with an elderly scientist named Khayyam.

Talk to the aranars

After talking to the explorer, who is very upset that he can no longer see the aranar, go a little to the east and talk to Aranaga, Aragaru, and Aranakin. They will perform a new Ritual with dried flowers.

This task will come to an end. As a reward, you will receive 100 Adventure Points, 10,000 Pestilence, and 20 Source Stones. Except the tick in Aranyaka book still won't appear. Plus, you won't get the trophy. To do this, you will need to perform one more hidden action.

How to unlock the Walnut Tree in the Garden achievement

Using the Paimon menu, scroll through the time to tomorrow or the day after tomorrow, and then return to the Mawtiyima Forest (western teleport) and plan east to the point shown in the screenshots below. There you will find a tent, not far from which Khayyam will stand (right next to the cliff).

Note: If Khayyam does not appear in the specified place, then try logging out of your account, wait 20-30 minutes and re-login. You can also try to find a scientist on the next real day.

Chat with the old man. He will thank you and give you a reward: Adventurer’s Tail Feather, 20 Primogems, 2 Experience Books, and 100 Adventure Points. Plus, you will unlock a secret trophy. In Aranyaka book, section "IV" will finally have a check mark.
