The Black Book is a mysterious, ancient tome with a cover made of dark, weathered leather that appears almost alive, subtly shifting under the light. Its pages are made of a strange, otherworldly material that glows faintly with an eerie blue hue when opened, covered in indecipherable Daedric script that seems to move when stared at for too long. The book is bound with tarnished silver clasps and features intricate, ominous carvings of tentacles and eyes that seem to follow the viewer, embodying the eldritch horror of its origin.
