Saleen was curious to know how the devil controlled his army. Although the demon dimension also had language and words and even cities, generally it was still desolated and uncivilized. Since they possessed so much power, demons had no interest in building fanciful cities. In the demon dimension, creatures that possessed the demon bloodline always ruled.
Supreme demons, demons, imps, demonic spirits; these demon bloodlines would always have an overwhelming advantage over magic bugs and beasts.
Since they were so strong and powerful, there was no need for fortresses. Armies did exist in the demon dimension, which made Saleen wonder what they were for. Mages did not have much records on this.
