Category: The coup d'état
Prerequisites: To play this quest, you must first complete the quest The prince's secret.
This quest will start automatically when you complete The prince's secret quest. Kurt and some Coin Guard soldiers will come to the chamber. Depending on your relationship with Kurt, he will want to kill Constantin or he will reveal to you the plans of his commander and he will decide to help you.
Warning: If Kurt betrays you and dies, he will obviously can no longer be your companion and you will also lose access to some side quests. Therefore, it is best to complete the Amongst the ghosts quest before starting this mission so that Kurt will take your side.

Lady Morange's house

If you haven't done the Amongst the ghosts quest and you are not Kurt's friend, he will try to kill Constantin. So you will have to defeat Kurt in a one-on-one fight. When you do that, you will be able to kill him or spare him. If you decide to spare him, Kurt will kill himself anyway.
Take Constantin down to the basement of the palace, to the cellar where he will be able to hide. Kill all the soldiers who stand in your way.
Note: Both Constantin and his advisors will find shelter in the same room, so you can do both tasks at the same time.
You will find the first one - Mr de Courcillon, on the third floor of the palace.
If Kurt is dead, you'll have to kill an additional soldier he's fighting with.
You will find the second one - Diplomatic Affairs Advisor, on the ground floor of the palace.
Take them both to the same cellar where Constantin is hiding.
Leave the palace and go to Lady Morange's house. If Kurt betrayed you then in front of her house, you'll come across a few more soldiers you'll have to defeat.
You will tell Lady Morange what happened and she will tell you that she can manage further on her own.
This task will be available only if Kurt is alive and he' s on your side. Find and talk to two messengers.
You will meet the messenger of San Matheus at the northern gate and he will set off immediately.
You will meet the messenger to Hikmet at the eastern gate and you will have to convince him to set off.
Try to do that task before you go to the commander Torsten's office in the barracks. That way you'll arrest all lieutenants and catch Torsten before he gets to port and gets away.
First go to the basement of the Coin Tavern where you'll find Lieutenant Werner and Lieutenant Olga.
Werner - You can try to convince the soldiers who are with him not to fight. Then you'll only have to beat the lieutenant.
Olga - You can try to convince the soldiers who are with her not to fight. Then you'll only have to beat the lieutenant.
Then go through the taver's kitchen to the Coin Guard Barracks. In one of the rooms at the top floor you will find Lieutenant Ludger. In this case, you'll have to fight both him and his guards.
There are several high level soldiers in front of the entrance to the Coin Guard Barracks, but you can avoid them by entering the building through the Coin Tavern.
The office is on the second floor.
Go there and read the message lying on the desk.
As soon as you get this task, run out in front of the main entrance to the barracks. You'll meet Torsten and a few soldiers there. The fight will begin. Ignore his guards and focus on Torsten.
Note: This is only possible if Kurt is alive!
When you defeat him, he will be arrested and put in jail, which will conclude this quest.
Another conclusion of this quest may be Torsten's escape on the ship. If Kurt is dead, you'll have to decide which city, San Matheus or Hikmet, you want to help. You will then receive a quest in which you will have to save the chosen city (Saving San Matheus or To the rescue of Hikmet). Unfortunately, the other city will be taken over by the Coin Guard soldiers and you will not be able to perform side quests for it anymore.
After completing this quest, you will be able to play the quests The suffering of Constantin, Saving San Matheus, To the rescue of Hikmet.
