The Delbarite Campaign showed the world the strength of Katolis's imperial army. It was an unexpected victory for many, as the Regular Battalion, the flower of Katolis's army, had been completely annihilated during the Battle of the Sand. Such a success can be explained only if we consider the great innovations that were put in place by Ezran and, above all, by General Gren. We recall that the General had been one of the few officers to survive the defeat of the campaign of Neolandia: the experience gained in that tragedy had convinced him of the need to renew the old system of battalions.

Pride of King Harrow and General Amaya, the Battalions were large groupings of 5,000 men, accustomed to marching, fighting and moving in formation. It was a perfect army for the defense of the border with Xadia, given its static nature, but it was slow, and therefore easy prey to faster opponents-as the Neolandian campaign had shown. General Amaya, aware of these problems, had thought of solving them by adding to the battalions the horse archers of Duren: but however skillful, the Durenian knights lacked cohesion and discipline, and weren't used to coordinating with bodies of heavy infantry like the Katoleans battallions. As soon as General Gren was officially appointed Marshal of the Kingdom, taking the place of Amaya, he decided to divide the bulky battalions into smaller and more mobile units, called maniples, each of 200 men and led by a captain. Ten maniples formed a Battalion, led by a Colonel: note however that the Grenian Reform Battalions were much smaller than those of previous years.

Each Maniple thus became able to act autonomously, ensuring greater tactical and strategic flexibility for the army.

Following the unification of Katolis and Duren, the Durenian army was also reformed: each Maniples was accompanied by 50 cavalry, making it a small army capable of acting independently. These cavalry groups, commanded by an Equestrian Lieutenant, could still be grouped if the general considered it appropriate to have more riders available (for example in case of field battle).

In addition, every three maniples were accompanied by a magician. The initial idea was to equip each maniple with a wizard, but mages at the time were very few, and moreover many had died during the Battle of the Sand.

Thus reformed, the imperial army was able to stand up to the guerrilla warfare of the Del Barite tribes, subjugating them.

We must also mention another military corps that would have assumed great importance over the years: the Imperial Guard, whose creation was strongly desired in particular by Queen Aanya. Until the time of King Harrow, the Katolis Royal Guard had been a corps of very few chosen men, almost all nobles: it was a corps more similar to a knightly order than to a real military unit. The Moonshadow Elves' assassination of Harrow had long since shown that this type of unit was inadequate to protect the king.

The Durenian and Katolean Royal Guards were then united to form the Imperial Guard, consisting of five hundred men. It was headed by Soren, the previous Captain of the Katolis Guard, with the title of Exarch (theoretically equivalent to the rank of Captain, but much more prestigious). It was no longer just a personal guard, but a real chosen body loyal to the sovereign and able to operate in battle with deadly efficiency.

The result of these important reforms was an army that was not as large as that of Harrow, thus managing to weigh less on the finances of the state, but was also much more effective.

To further demonstrate the validity of these reforms, the imperial army of Katolis remained virtually unchanged for another two centuries, until the great military reform of Callum I, which definitively abolished the system of battalions.

Until then, for two hundred and ten years, the army devised by General Gren would represent the most disciplined, effective and feared military force on the continent.
