Tom Forbes and Genevieve Gaunt are also joining the cast toplined by Tom Cullen.
According to Entertainment Weekly, History has renewed the series with a new showrunner, Aaron Helbing taking over for Dominic Minghella.
"In the face of ever-increasing competition, we're proud of History's track record of producing signature drama series that are epic in scope with complex characters," History programming executive vp Eli Lehrer said in a statement.
"Whether it's the legendary Knights Templar, the extraordinary tale of medieval Norsemen, or the story of a formerly classified United States Air Force program investigating UFOs during the Cold War, these series reflect our commitment to bringing the defining, big canvas stories of history to life. We look forward to offering our viewers a grittier, darker Knightfall in season two and welcoming Mark to the cast," he added.
