I'm starting out and have encountered the Spartans first. I have chosen to help them by undertaking their quests.
However, when I reach a fort in a Spartan controlled area, the location objectives include burning War Supplies, which would weaken the control in the area, and the guards there attack me on sight.
Can I burn these supplies without it harming the Spartan war effort?
Or am I right to assume that because it's an objective required to complete the location that you don't really choose a side in the war, and everything is fair game in Forts?
