Result
The Nilfgaardian and Redanian forces had fought many bloody yet indecisive battles in Velen from which both sides had to retreat without collecting their dead. On one such field Geralt encountered a group of looters robbing the corpses of the fallen. In another time and place he might have merely grit his teeth and continued on his way. Yet conditions in Velen were harsh and other sources of sustenance few - so he decided to swallow his revulsion and defend these desparate men from the monsters stalking the battlefield.
