Description: 

I found the cave Duda while exploring Aanthrin, killed all the bandits there, and freed their slave, Ji'Zirr. When I got journal updates for doing so, I thought I'd just completed a short quest, but after looking at my journal I saw I'd activated a quest called "Imperial Legion: Freedom At Any Price". My character is not a member of the Imperial Legion, and it would be impossible to complete without joining, so I don't think I should have this quest.
