Starz will expand the world of Outlander with a prequel series now in the works.

Outlander showrunner Matthew B. Roberts will return to write and executive produce the prequel series. Also returning will be executive producers Ronald D. Moore and Maril Davis under their Tall Ship Productions. Sony Pictures Television will be the studio. Speculation about an Outlander prequel with Roberts at the helm started last summer when Deadline reached out to Starz about the project.

News of the prequel series comes ahead of Outlander’s Season 6 premiere on March 6, which picks up shortly after traumatizing events of season five. When viewers last saw Claire (Catrionia Balfe), she had returned to Fraser’s Ridge after escaping a violent encounter with Lionel Brown. Claire and Jamie (Sam Heughan) were facing the threat of a looming Revolutionary War, and a decision as to what is best for their family.
