DAMIAN IN THE CLUTHCES OF MEMENTO! Deep under Gotham City lies a subterranean echo of a lost time. This abandoned world has lain uninhabited for decades...until tonight. Now, Damian Wayne is the sole human resident of these abandoned catacombs...imprisoned by the entity known only as Memento. A father is desperate to track down his son, but will Batman be able to descend into the bowels of the city in time to save Robin? Or will the Dark Knight's mind spiral into madness first?
