Plot

BATMAN'S WORST FEARS BECOME REAL! Spirited away from a city that believes him dead, Batman has been brought far from Gotham and deposited in a desert of legend. Possessed by an Azmer demon and rapidly losing his own identity, he must now cross this mythic landscape on a vision quest. With no water, no supplies, and no one to save him, Batman is left with two choices: burn out the demon or be left as bones in the sand. Meanwhile, the Orghams' master plan is finally fully enacted as they use the Reality Engine to make all of Gotham forget there ever was a Batman. Bear witness to Batman’s worst fears made manifest in "Elegy of Sand," part one!
