Given everything we know about the Masonic connection, I don't believe it's a coincidence that POTUS is in Scotland of all places, on Friday 13th during a new moon / lunar eclipse.
In my digging over the years I once explored moon magic (Golden Dawn is the source - understand this may be unsavory for some anons; FYI: the GD cribbed rituals from all over the shop). The moon is referred to as being the source of dragon energy. Specifically, magic that invokes the moon on a full moon utilises the 'tail of the dragon', whereas new moon magic utilises the 'head of the dragon'. Summoning the tail of the dragon is sludgey and dark and a bit horrible - like wading through treacle, whereas summoning the head of the dragon gives one the ability to utilise the power of the dragon - think Daenerys in full flight. Whether POTUS engages in such ritual is open to debate. Suffice to say that the head of the dragon on an eclipse is powerful stuff.
The symbolism of POTUS in the Queen's backyard, at the font of masonry, on such an auspicious day will not be missed by the cabal.
