I am not an expert but some of the comments in Intelligence gathering are stretching my understanding of the social fabric of Mythic Europe.
My understanding is that just about everywhere something like the Feudal System is in effect, where superiors are obligated to look after inferiors, while the inferiors are supposed to owe service to the superiors. God is at the top, followed by Kings and Popes, and so on down to peasants/bondsman are at the bottom.
And to some degree legally, the inferiors are under the control of their superiors, and thus the inferiors and their actions are the responsibility of the superiors.
Even in inter-personal relationships, such as parent and child or master and apprentice, the actions of the child/apprentice reflect upon and are the responsibility of the parent/master.
I have always though Covenants were arranged in a similar fashion - the grogs enjoy the amenities and protections of the Covenant grounds, and in turn owe service to the Covenant's masters (the Magi). Thus a grog's actions reflect upon the Magi, and technically are the Magi's responsibility,
Usually this isn't much so long as they stick to the Covenant grounds, but should a grog leave the Covenant grounds and do stuff, it is implicit that the Magi at the very least approved, if not actively directed the grog. At least in the legal sense.
So woe-betide if the grog interferes with another magus or Noble.
My understanding is that as the superior, the Magus is by default responsible for the inferior's (aka grog's) actions. The mage would have to defend the grog's actions, and it is really embarrassing admitting that you have lost control of your inferior. Few would admit to such a weakness.
At least, in the back of my head that is the way I have been playing it up to now (there was one asset that was prepare to be disposable, but that should be a rarity).
Am I significantly wrong?
