Create a dark and mysterious logo for the 'Department of Haunted Authors

Create a dark and mysterious logo for the 'Department of Haunted Authors.' In the center, depict a ghostly quill pen, with ink trailing off to form a faint, spectral mist. The quill should appear as though it is writing in mid-air, with the mist forming the initials 'Kon Murshid ?.' Surround the quill with ancient, slightly open books, their pages curling and giving off a faint glow, as if imbued with a supernatural presence. The overall color palette should include deep shades of black, gray, and indigo, with subtle highlights in silver. The background should resemble a misty twilight, with hints of eerie, swirling fog. The logo should convey an eerie, gothic atmosphere, reflecting the haunted and literary nature of the department.
