The fortress has become quite famous due to the decisive battle of the Succession War having been fought here; since then the ruling nation has made sure to keep it well staffed.
In the events prior to the Toran Liberation War, Tir McDohl passed through here with his companions, Gremio, Cleo, and Viktor. Fearful that general Ain Gide, currently stationed at Kwaba, would recognize them, Cleo suggests that each person use an alias. While they manage to get past, Ain Gide hints that he knows who Tir is, and tells a fellow soldier, Rosh, that it is not a big deal. After Tir and the group passed through, the doors of Kwaba would remain locked until the final stages of the Liberation War.
