First in all

There was a large building in the Imperial Lightning Fort, and its proximity to the Titan Tower should tell everybody just how important that place was. 

Unlike most buildings in the fort, where soldiers could go in and out without a problem, there were guards at the front gates, and their aura put them at the Wave Champion rank!

It had two words unleashing an imposing power in the front, and every soldier would show deterrence when they looked at them.

Military Investigation Bureau.

The Military Investigation Bureau was in charge of all types of criminal investigations across the Collapsing Lightning Sector, and their power was massive. A single order from them could deprive a Count of all their belongings and mark them as a criminal or, even worse, a traitor. They answer to no one but the Collapsing Lightning Duke.
