The TV series is kicking off its 15th and final season this fall, and The CW has released a promotional poster that appears to hint at what's to come for the long-suffering, demon-hunting Winchester brothers.
"As it is written, so it shall end," the poster reads.
In the season 14 season finale, Chuck -- who we learn is the creator of all -- snapped his fingers and released demons from hell, leaving Sam, Dean and Castiel to fight off the monsters.
Already speculation has begun on social media about the poster's symbolism, and what it says about the final season: Will Sam and Dean Winchester die?
The stars of the show are also using attention around the series finale to help provide relief for victims of Hurricane Dorian.
