The interrogation focused on gathering information on the Thunder Kingdom's troops, since the information provided by the academy was extremely limited. A few of them even felt that, if they could dig out the troop's defense formations from the merchants, they could possibly complete the optional tasks with ease.
The notion was perfect, but reality was nowhere near that. No matter how much they hurt the captives, they could not gain any information. They did not know if the Normans really did not know, or if they were just extremely stubborn.
Of course they managed to gain some random bits of information, such as the number of troops the enemy had. The Thunder Kingdom currently had two large infantry squadrons and one medium wolf cavalry squadron stationed at the border, totalling up to about five thousand troops.
