In the world of the game there are multiple places, like for example Wyzima or Novigrad. Your name is Gotrek and you may also meet some NPCs (Gerrudir and Gwaigilion). Each of you is in one of the places. You are free to move to other locations.
Keys
Some of the places can require a key to enter. If any of the characters present has the key required to open a place then the place is automatically opened and everyone enters the place. For most actions you need to enter a place, especially actions like telling another character something or asking him for something.
The keys can be found in various places. (You do not have to enter a place to pick up a key).
Patience
Each of the characters, including yourself, has a parameter called "patience". When entering a new place it is set to the max value (3). After every action performed the patience is decreased. When one runs out of patience he moves to a different location. Note, however, that a character can move elsewhere before he runs out of patience, especially if nobody has the key required to open a place they are in.
If a character asks another character about some information he expects an answer, therefore his patience is not decreased at this very action.
Listening
When you see the other characters then you can see/hear their actions and will be notified about them. Also when you tell for example Gerrudir something and Gwaigilion is present there, then Gwaigilion will hear you.
Believing
The NPCs are simple folks. They usually believe what they are told.
Attacking
Each character may attack the other characters. If he succeeds - he may obtain some keys of the attacked one.
