Mountains of Ket

Your society is suffering from frequent attacks by forces from the east, lead by Vran Verusbel and princess Delphia. You have been charged with murder, and have only one option to escape death - travel east and kill Vran and Delphia. The only safe way to cross the mountains is to find a secret path leading to an underground passageway. You are not fully trusted, so an implant known as Edgar is fitted - it will know when you are not sticking to the task, and kill you if that happens.
