Result
Holger Blackhand had stolen a great many priceless goods during his many plunderous raids. Yet none of these foreign trinkets could rival the carved horn passed down to him from his ancestors for his affections. The warriors he had recently banished must have known this - for they took this horn as an act of vengeance against Holger. Holger had let it be known that whoever found his prized possession would receive a hefty reward. Geralt, who could track thieves and stolen goods like no other, decided to investigate.
