Cardinal is a position within the Lancea Sanctum. This is a rare role for a Kindred in the covenant to take, as it requires both the "big picture" thinking and leadership of an Archbishop and the attention to minute details (training Priests, overseeing Apostolica) that a Bishop is typically responsible for. In effect, it is a combintion of the position of Archbishop and Bishop. Cardinals make sweeping decisions on Sanctified policy, and their decrees "trickle down" to the street level, where the action actually happens. Cardinals are typically spread thin due to all the multi-tasking they have to do, but some manage to make it work. Cardinals have the highest possible Status within their covenant (provided they can manage the multi-tasking and don't go insane).
Alternate titles for Cardinal include: Vicar, Pontiff, Pontifex
