"Within the shadowed halls, where whispers echo
and fears manifest, 'The Raven Man' weaves his
dark ritual. With a gesture, life unravels, souls
seep away, leaving only the chilling echo of their
last breath. Here, in the grip of his ominous
power, even the bravest hearts falter, as the
essence of life itself is drawn into the void."
