The Empire's regular legions amounted to a total of ten.
The First Legion and the Eighth Legion defended Seawindon.
Another four were stationed at the frontiers.
The Second Legion, positioned at the Red Fortress in the Northwestern corner of the Nesserite Empire, resisted the northern orcs and the western lizardmen.
The Third Legion, stationed at the border of the Eastern Province and the Karl Plains in the Scarlet Fortress, opposed the northern orcs and the northeastern Barbarian Tribes.
The recent orc wave was precisely a combined assault by trolls, barbarians, and orcs that breached the outer wall of the Scarlet Fortress.
The unprepared Third Legion suffered heavy losses and could only defend the inner wall to ensure the fortress did not fall.
It was also for this reason that without any reinforcements to support them, the Third Legion was powerless to prevent the orc army from passing the Scarlet Fortress.
