Leave the warehouse
From Create Your Own Story
Knowing that the other men are far too busy worrying about the dangerous barrels in their hands to realize right away that you are not following them, you wait for them to have a head start. After a moment, you close the trap door with your foot and place your heavy barrels of warpstone on top of it just in case they try to come back and see what happened to you. You then walk out of the warehouse into the warm night. You hesitate between warning the legitimate authorities (the city watch) or your employer (the Church of Sigmar).
