How to start a task

Before you can take on this quest, you will need to meet a number of conditions, namely:

• Reach at least Mastery level 26.
• Complete the adventure mission "Ancestral Drill".

Having dealt with the indicated requirements, wait for the message from Velt to arrive and answer it, which will lead to the start of the mission. Now head to the Creation Platform Dimensional Anchor located on Everwinter Hill.

Find out what this unknown signal is

In the marked area, you will need to examine some frozen statues of Antimatter Legionnaires. The first in the form of a centaur is on the left side. A spark will glow near it - interact with it.

The second is also located to the left, slightly ahead of the previous one. Look around, you won't find anything. Now go to the right side and inspect the second centaur next to the Echo of War portal.

After that you will receive a message from "Techniques of the Interstellar World". Ask the other person to send you a link.

How to find the "Chronicles of Belobog" in the closet

Having determined the source of the signal, return to the Common Car and talk to Velt. Choose the first dialogue option marked with an exclamation point. During the conversation with Himeko and Yang, you will receive a message again. You can choose any answer.

Then move to the Administrative District, go east and go to the Qliphoth Fort. Find Armor and talk to her about the history of the planet. She will advise you to read the book "Chronicles of Belobog", which can be found in the closet on the right side.

Next, return to the Common Car again and talk to Velt. You will receive 15,000 credits from him. Now go to Asta in the Main Control Zone and talk to her about the Finder.

This will complete the task. As a reward, you will receive 40 Star Jades, 250 Mastery XP, 100 Shields, and 6 Adventure Logs.
