In Cairo, psychiatrist Aser and his mysterious companions uncover connections between secret files from the 1967 war and experiments seeking to harness ancient Egyptian divine powers. Their path opens onto the Duat, an underworld filled with shattered minds and wandering battalions seeking either return or eternal rest. As a hidden project's links to fallen soldiers and family secrets emerge, guilt, duty, and collective trauma become part of a struggle for survival. This is the fourth part of the Rouhani series, in an Arabic-language edition.
