Game of Thrones has posted a teaser trailer for the episode 2 of season 7, 'Stormborn', seeing the tension ratchet up as word spreads of Westeros' new arrival.
The title of the episode clearly points to Daenerys, and indeed it seems she is on people's minds in both the North and South.
"A Targaryen cannot be trusted," a lord warns King Jon in Winterfell, while Cersei is heard prophesying: "The Mad King's daughter will destroy the realm."
