===His Imperial Majesty's Secret Service===
When dark forces rise, the Secret Service is there to cut them out, quietly and stealthily. They are the secret agents of the Emperor, acting on his authority when all peaceful measures fail. When mad psykers arise, they are there to take them out. When corrupt governors starve their people, the Special Agents are ready to remove them. Notably, they are not as extreme as their ''Warhammer 40k'' counterparts (the Inquisition) and are mostly focused on more James Bond-like secret agent action.

The Secret Service makes use of several different specially trained operatives, apart from general Special Agents. These individuals are drawn from the elite of the elite and trained at specialized combat schools. 

'''''Callidus School''''' is still dedicated to infiltration tactics, scouting, information gathering.

'''''Eversor School''''' is for assault, designed to take on even the strongest foes in single combat, and receive a number of physical, mental, and cybernetic enhancements.

'''''Vindicare School''''' is dedicated to the mastery of long-range, sniper-type weapons. The noble fallen knight LIVII belonged to this organization. 

'''''Culexus School''''' trains specialized individuals who are capable of uplifting morale to immense levels and can increase the performance and natural healing abilities of their companions, despite lacking psyker capabilities. AKA, the reverse of the Pariah trait. These individuals are incredibly rare, but make highly effective team leaders.

All are recruited from existing special forces and receive the Inquisition's best training in general operations before proceeding on to their permanent combat school, in which they receive training in their specialized area.

After training at their respective schools, they go on to a third phase of training, a cross-disciplinary school for team building and mutual advancement that teaches them to recognize and use each other's strengths, thus eliminating all their individual weaknesses. After graduation, they are known as Imperial Special Forces, second only to the Astartes in terms of sheer effectiveness.
