The kyrians of Bastion serve a unique purpose in the Shadowlands, and without them we will be unable to replenish our forces. Should we wish to stand triumphant in Maldraxxus, we must extend some of our might to aid them.
Travel to Bastion and provide support, so as to stabilize their situation. In doing so, we will secure the future of our armies and cut off the supply to our enemies.
War is not always fought on the battlefield, but often in the means of replenishment.
