The main secret of Kahal in Baldur's Gate 3 is to find the box behind the bookshelf in the servant's quarters in the Druid's inner sanctum. Open the box and you will see the letter inside. Then you can complete it according to the content of the letter.
The first is in the servant's quarters of the Druid's Inner Temple . After entering, you can find Kahal's box behind the bookshelf.
Then open the box and you will find Kaha's letter and learn that she is a servant of the Shadow Druid.
To help the Shadow Druid control the camp , there is also an agreement to meet at the swamp dock .
Afterwards, the player will find the swamp to the south of the plague-infected village according to the specific location, and jump over to find the big tree to the south.
Players need to defeat the little devils and tree spirits near the big tree (the fire system is more effective) and then continue to find the letter in the gap between the red circle trees.
After that, you can go back to find Kaha, confront him and persuade him , or you can kill him without triggering a confrontation in the Druid camp.
