An intricate dark fantasy logo design features a highly detailed demonic goat skull with twisting, curved horns at the center, framed by an ornate pentagram and concentric magical circles inscribed with dense arcane runes and occult symbols. Gothic blackletter text "Dol-Goldur" arches above in weathered gold lettering, while a tattered banner below proclaims "Necromancer Store" in jagged script. The skull exhibits cracked, weathered stone texture with bone-deep crevices, horns gleam with metallic copper sheen and subtle engravings, surrounded by flickering candle flames and shadowy wisps. Set against an aged parchment background with faint stains and tears, the composition employs copperplate etching style with woodcut crosshatching, 3D embossed depth, dramatic chiaroscuro lighting casting deep obsidian shadows and fiery highlights, sepia and obsidian tones dominating the mystical, ominous atmosphere of a vintage occult tome illustration, every rune, texture, and highlight rendered with masterful ink precision beyond human perception.
