Mind the gap — and the White Walkers too.

London commuters have found themselves face to face with the sights and sounds of Game of Thrones as part of the promotional blitz for HBO’s hit fantasy series, which kicked off its seventh season Sunday night (early Monday morning across the pond).

Marking the show’s highly anticipated return, King’s Cross railway station played host to a string duet performing the Game of Thrones theme song, costumed White Walkers roaming the grounds (including the fearsome Night King), service information signs referencing the fan favorite character Hodor, and a replica Iron Throne.

Check out a video of the string duet and more photos below.

Game of Thrones airs Sundays on HBO.
