While the fictional characters at Castle Black on HBO’s “Game of Thrones” have to deal with white walkers, sieges and giants, the nonfictional cast and crew members working on the Season 6 set don’t exactly have it easy, either. Production of the series had to be rescheduled after nature pushed back against the actors and crew.

According to Entertainment Weekly, the set that plays home to the watchers on the wall in Northern Ireland’s Magheramorne Quarry became unstable and unusable for a brief time when the area’s heavy rainfall disrupted the area’s seismic profile, leading to a rockslide.

“Once people saw the small pebbles start to come down that turned into slightly larger pebbles, everybody made the group decision to immediately step away,” showrunner Dan Weiss told the outlet.

Luckily, nobody was hurt. And the change in the show’s tight production schedule actually allowed the producers more time to work out the scenes at Castle Black while professionals secured the area and protected against another rocksliding incident. Because of their work, the series’ season premiere date wasn’t delayed at all.

Fans are doubtlessly thrilled to hear the Castle Black set wasn’t destroyed and that none of the scenes filmed there suffered, given that it will likely be the location where the show’s biggest cliffhanger of Season 5 will be resolved. In the finale, [SPOILER ALERT] beloved character Jon Snow (Kit Harington) appeared to be killed at the hands of mutinous members of the Night’s Watch. The character was the Lord Commander of Castle Black, which means if fans are right and the character will be brought back in some way, that’s the set where it will most likely happen.

HBO released another trailer for “Game of Thrones” Season 6 Sunday to tease the series’ return. However, it continued to play coy about the fate of Snow by keeping the character absent from the new footage. It appears that fans will just have to wait until the show returns for Season 6 April 24 to see how it all shakes out in the end.
