Embrace the Darkness: 1970s-Style Book Cover

A dramatic 1970s-style book cover featuring a woman trapped in the grasp of dark, writhing tentacles from a mystic, evil creature. She is being pulled into a glowing, swirling green magical vortex that emits an eerie, supernatural light. The setting is a collapsing wooden cabin, with shattered debris flying through the air. In the foreground, a terrified man and young boy stand watching the horrifying scene, their expressions frozen in shock. The color palette is dark and moody, with vivid neon green from the vortex contrasting against muted browns and grays of the cabin. The design has a vintage, 1970s aesthetic with bold typography for the title 'On Stygian Tides.' Highly detailed, dynamic, and cinematic. Size specification: 6x0.49x9 inches.
