The Lost Kingdom is a Batwing storyline written by Judd Winick with art by Ben Oliver and ChrisCross. Following the timeline reboot in Flashpoint, it establishes his continuity in the DCnU. It's the first arc on Winick's Batwing volume, the character having previously appeared only in Batman Incorporated. This storyline leads directly into the Night of the Owls crossover followed by their second arc In the Shadow of the Ancients, and Batwing joins the cast of Justice League International in their second volume Breakdown. Although the collected edition only carries the series' first six issues, the beginning arc actually ends at issue eight.
