New TV show and Mary Queen of Scots

There's this new TV show I found on Hulu called Reign, its about Mary Queen of Scots and the time she spent in the French court while being engaged to the prince. It's totally fictionalized and, though I'm not a history buff, I'm fairly sure there is not an ounce of truth in the plot. The show itself isn't bad, if you aren't concerned with historical inaccuracies, however, they do mention an aspect of court that I haven't ever really heard of: the queen has a man who can read the prophecies of the future. I'm almost 100% sure that this is completely fictional, because of the power of the church at this time, but it does make me wonder where the aspect of magic went for this culture. Because I don't think that something so prevalent for such a long time could disappear completely, and that it would pop up in unexpected places of social life, although I don't know what these instances would be.
