I have gifts for both Perun and LPC. Message me and I’ll figure out how to send them to you. There is a much deeper connection to France, than the films, although you are on the right track. Durendal is also connected to this sword."Hangs by a horse hair above every rulers head" , but is not this one. This is Galgano's sword.
And "The french connection" is a classic. In that one G. Hackman comes to France yet does not join the Legion (that he does in "March or die" ) but fights drug dealers, hence the "connection" in the title.
Both movies are great.
