st pierre en faucigny
so to be clear
when you get the city you can choose a sanctuary to copy only at that moment
if you will not choose a sanctuary right away
then at the end of the game you can choose any location but not sanctuary
Sorry.. i delete my former answer which was confusing..
With the city of mirror, you choose which city you copy AT THE END of the game... if you choose to copy a sanctuary, then you draw the loot cards
