Sabotage

Sabotage is a secondary quest in. It only occurs if you saved the elf and enlisted him in The Black Sheep quest.

Walkthrough
After you visit Dravograd, travel down the path and this quest will start. Men from your army have begun to grow sick and over the course of a few days, five have died. From this you will lose five.

Later, the elf you helped in Elsterberg, is brought before you, as he is guilty of the crime, proudly openly admitting it. As a punishment, you hang him right there as taking him to the Lyrian capital would be an open spectacle, fulfilling his desire for him and his crime to become infamous.
