Glyngatwg
From Tardis Wiki, the free Doctor Who reference
Glyngatwg was a village in Wales. It had a pub called Y Pren Marw.
In the cliffs above Glyngatwg, there was a fairy circle that in one timeline the Doctor stepped on, with scrolls inside that Ruby read out, causing the Doctor to vanish. (TV: 73 Yards [+]Loading...["73 Yards (TV story)"])
