Seven Signs - Seal of the Emperor

Talk to Iason Heine in Heine . He will begin to read the contract, and immediately Merchant Mammon will appear nearby.
Talk to the Merchant of Mammon. He will briefly tell you that the Emperor asked them for help, and so they entered into a contract.
Talk to Jason Hein and tell him the information you received from the Merchant of Mammon. Jason will send you to look for the Promise of Mammon at the entrance to the Necropolis of the Apostles.
Head to the Necropolis of the Apostles, at the entrance you will find the Promise of Mammon, which looks like a standard Guardian of the Ziggurat Portal. At the same time, it is advisable to be registered for the Lords of the Dawn at the “7 Seals” event.
Mammon's promise will teleport you back in time (one and a half thousand years ago), inside the necropolis, and a surprise will await you: a meeting with Emperor Shunaiman and his bodyguards (because you are in the past).
Shunaiman, the former Emperor of Elmoreden, is seriously wounded and resting in the necropolis.
He gives you a task to help Anakim: launch the Emperor Seal Device and destroy the 4 seals holding Anakim back. To do this, he will give you the Holy Sword of Einhasad (a shadow item lasting 5 days) and the Holy Water of Elmoreden.
The further path to the necropolis is blocked by a red door. Take it to Target, use Elmoreden's Holy Water and the door will open. The sword given to you has P.Atk 7 and a very strong special skill “Einhasad Attack”. Place it and water on the hotkey for easier use.
When you enter the instance, you will be attacked by several Lilim mobs. Kill them exclusively with a special sword attack (can be found in the item skills of the “Skills and Magic” window). Be very careful and monitor your health.
The general rule is that blue doors are opened by clicking on them, red ones by Holy Water, and purple doors by clicking the Wand of the Imperial Mage.
Making your way through the mobs, you will sooner or later stumble upon the body of the Imperial Mage Elmoreden. Click on the corpse and receive the Court Mage's Wand.
Use the Court Mage's Wand to open the next door. Kill mobs with the given sword and move forward.
When you see the Oracle Gatekeeper, make your way to it and click on it with your mouse. He will teleport you to the next room.
After watching the video about Anakim, you will witness her fight with Lilith. During the battle, you need to activate four Printing Devices and take possession of 4 binding seals from them.

Each device contains a seal, which must be taken to Emperor Shunaiman. Devices around them contain a field that causes damage. Be very careful and monitor your health level.
After receiving all 4 seals, return to the Emperor and he will give you 2 clues on how to find the Seal Scripture in the future.
Talk to the Emperor's Guardian Leon - he will teleport you from the necropolis (and at the same time - from the past to the present).
Go to Heine, to Iason Heine, and give him information about the clues.
Jason Hein will invite you to meet with Dawn Witness Franz, but to do this you must first talk to Priest Oud in the Temple of Aden.
Go to Town of Aden, in the Temple of Einhasad, find the Priest of Oud and talk to him. The quest is over.
