In Last Knight on Earth, Bruce Wayne wakes up in Arkham Asylum having never become Batman and sets off on a quest to piece together the mystery of his past and to track down the unspeakable force that destroyed the world as he knew it.
Like several other Black Label titles, the miniseries is intended for mature readers. DC launched the line to house high-profile stories that take place outside of the current DC continuity (see “Dc Launches Imprint for High Profile Stand-Alone Stories”). Last Knight on Earth was among the titles announced with the line launch, but details weren’t available at that time.
