Journal
Luckily Geralt managed to get his hands on just such a pass and from then on could cross the Pontar border at will. I hope he did not abuse this privilege, jumping back and forth across the border, making faces at the poor wretches stuck on one side and taunting the guards who had no right to stop his antics. He mentioned nothing of the sort, true, but that's just the kind of thing one might choose to keep to oneself.
