Diablum (BxB)

When Clément (kleh-mahn) accidentally awakens an incubus named Noctivane during an expedition in the catacombs of Paris, an ancient prophecy is awakened. Drawn into a forbidden love that defies the laws of both heaven and hell. They soon discover that the beginning of their love would bring the end of the world, as the massacre reopens the centuries old catacombs for use.

The Catacombs of Paris, a vast underground ossuary, remain one of the most mysterious and haunting sites in the city. Initially created in the late 18th century to alleviate overcrowded cemeteries, the Catacombs house the remains of over six million people. Today, they are historic sites where the state of the catacombs is well-kept and partly open to the public. Tourists can visit a small section that is accessible, where neatly arranged bones and skulls are displayed along narrow tunnels.
