Mark of Sentinel
The bearers of the Mark of Sentinel possess a number of powers designed to keep others from coming to harm.
House Deneith humans bear the Mark of Sentinel and employ its power in their Defenders Guild. While the guild is mainly concerned with protection for individuals of high status (and coin to spare) but they also have special agents known as sentinel marshals who are able to carry their jurisdiction across borders. Just as with their marked kin unmarked members of House Deneith are mainly bodyguards, but get by without the aid of magic.
