Combat
Although many consider them as "secret agents" of some sort, they are hardly different from an average City Guard. However, their armor is slightly better and Penitus Oculatus members can also be skilled with magic and take you down with an unexpected Spark or Ice Bolt attack. You can still take down many with ease in the Dark Brotherhood quest, "To Kill An Empire."

Behind the scenes

 * Penitus Oculatus is Latin for "having inward sight," or, literally, "inward eyed."
 * After the Dark Brotherhood questline, some of the remaining Penitus Oculatus can be killed without accruing a bounty. Strangely enough, the town guards assist in killing them.
 * Penitus Oculatus Agent can also be shown as the author of a contract.
