Hi @violentmrtino thanks for the video provided.
So from the video I can see that you are on the quest 'Madness of King Charles' and that you require the two keys to open the sanctum door.
This is strange as after you complete the quest 'Trial by Fire' there is a cutscene and then you enter the building that King Charles is in. He is locked behind a door which requires the two keys to enter.
What is strange is that you have somehow ended up back outside the village. Can you please explain what happened when you completed the quest 'Trial by Fire' and how you came to end up back outside the village?
