Of course, this doesn't mean they were completely inactive. At the West Gate Tower Fort of the Komeer Kingdom, they had assembled a corps of three thousand men from the Purple Dragon Legion, led personally by their heir, Crown Princess Tainalasta. They were certainly not there just to fill numbers.
As soon as the Conqueror Army made a move, they would definitely follow deep into the Goblin Margins, scavenging for advantages, something every power liked to do. Even the Komeer Kingdom, which was known as a force of good, was no exception. As for whose loss they would profit from, that would depend on how the war situation developed.
Even if the Conqueror Army were defeated, they could still take the opportunity to absorb some of the defeated soldiers and refugees to strengthen themselves. This was an advantage of their position as a human force of good.
