“That’s the whole point of Starfleet Security—to keep us secure. Because if we can’t protect people who need it the most, what the hell are we even doing?”

—Commander Ellen Landry

“Impossibility of Reason” is a new mission following the story and events of “Plausibility of the Possible.” After Klingon captives from the Priors World skirmishes escape from custody, it’s a race to get back in time to aid the Buran against further Klingon attacks. With Commander Landry and her security team along for the battle, it’s up to you to rescue Buran, save Priors World from invasion, and stop the attacks by the Klingon Captain Aakar! Experience the events that led Ellen Landry to become the hardened Chief of Security aboard the U.S.S. Discovery.

You can access this mission from your mission journal. Captains of all factions will be able to play “Impossibility of Reason” when Rise of Discovery arrives.
