That sound you hear is three different fandoms exploding with happiness.

Hogwarts visited Westeros and brought Clara Oswald along for the ride when Maisie Williams shared a selfie on Instagram (seen above) of her posing with Game of Thrones co-star Hannah Murray (who plays Gilly), Daniel Radcliffe, and Doctor Who’s Jenna Coleman.

“I think this photo is gonna make the world implode,” Williams wrote, not quite exaggerating. “Last night was really great #sdcc2015.”

The foursome appeared together at the EW Comic-Con party on Saturday night (Radcliffe even played ping-pong). For more pics of stars partying at Comic-Con, head here to see photos from the red carpet at EW’s big bash and snapshots from inside the soiree.
