Protection
The Penitus Oculatus was a cohort of Elite imperial Soldiers  well-trained in melee combat, and Magic. Following in the example of The Septim Emperors Protectors known as The Blades, the Penitus Oculatus served as King Ernst's personal bodyguards, and therefore, was tasked with protecting him against any threat to his safety. The Guard as a whole was divided into two pairs, each brandishing their own unique Combat Style[15] such as Being, Spell Swords, and the common shield and sword.[5]

In the aftermath of The Great War, King Ernst ordered the Construction of a new Imperial Royal Guard, one that would go on to Competely Replace the blades and Protect the King through out his reign over Tamriel

The Penitus Oculatus, it would be made up of top trained elite Imperial Soldiers Chosen By The King himself to Protect him from any threat to both him and the Empire
