[X] It is long past the time to meet and deal with Faceless Men of Braavos.
-[X] They are a part of the realm now - and so they fall under the laws of Scholarum, they shall submit all the lore they have. --[X] Ensure all the lore of Faceless Men is submitted to review, but with how strong of an organization they are, they may desire for trade instead. --[X] Trade for artifacts and/or magic items, if they possess any.
-[X] And while we are at it... Their organization shall either have a tight set of limits on what they can do within the confines of your Empire - or have no place in it at all. We cannot afford an unaffiliated cult of Assasins running around. --[X] Talk to the leadership of the Faceless, and try to find a middle ground - we'd waste far too much time purging them, after all, and there will always be better targets to turn their ire towards, than mere mortal men.
