The 168-year-old mystery of Britain’s Royal Navy’s HMS Terror has been solved just as AMC is readying an anthology series inspired by the disaster. An Arctic Research Foundation team has located the long-lost ship of British polar explorer Sir John Franklin in pristine condition at the bottom of an Arctic bay, The Guardian reports.

“We congratulate the Arctic Research Foundation on finding the Terror 168 years later,” AMC President of Original Programming Joel Stillerman told Deadline. “Apparently they’ve never heard of a spoiler alert.”

AMC’s The Terror, based on the bestselling 2007 novel by Dan Simmons, is a fictionalized account of Franklin’s lost expedition of HMS Erebus and HMS Terror. Set in 1847, it tells the story of a Royal Navy expedition crew searching for the Northwest Passage and attacked by a mysterious predator that stalks the ships in a suspenseful and desperate game of survival.

Written by feature writer David Kajganich, who co-showruns with Soo Hugh, the 10-episode series hails from Scott Free, Alexandra Milchan’s Emjag Productions, Entertainment 360 and AMC Studios. The Outlander co-star Tobias Menzies was recently cast as a lead in the drama, set for a 2017 debut.

There are no immediate plans to use any of the findings from HMS Terror, whose discovery comes two years after Erebus’ remains were located, though the news would give the AMC project some unexpected free pre-launch awareness.

All 129 men on the Franklin expedition died. Search teams continued to look for the ships for 11 years after they disappeared, but no traces were found– triggering all sorts of theories, including the supernatural take in Simmons’ novel.
