Requiem Knight of the Vampire. Resurrection. Dance of Death

The story tells of the adventures of German soldier Heinrich Augsburg in the afterlife. Tormented by feelings of guilt, first for betraying the ideals he serves, and later for betraying his beloved, he perishes on the Eastern Front. After being... shot in the forehead, Heinrich finds himself in Resurrection, a planet where our familiar world is reflected in a distorted mirror of decadence. Time flows backward there, fiery seas rage in place of earthly continents, high technology serves obscurantism, and each person embodies some form of evil, depending on the nature of actions committed in earthly life. By chance, the main character avoids immediate death at the hands of zombie marauders who encounter resurrected soldiers from all eras. Heinrich undergoes training on the dark side of the Moon, swears allegiance to the Lords of Infinity, and thus joins the ranks of vampire-knights. They are the elite of Resurrection.
In this Dantesque purgatory, descendants and ancestors, hunters and victims, ordinary people and historical figures often meet, sometimes changing roles. There are no innocents here; Resurrection, like a cauldron, boils with wars and political intrigues against the backdrop of the unending enmity between the Gods of Limbo and the Lords of Infinity. Moreover, a powerful cataclysm approaches - the Great Cosmic Tide.
The knot of duty, guilt, love, friendship, and betrayal tightens ever more...
