Its cover is crafted from deep, obsidian-black leather, aged and worn, hinting at the forbidden knowledge it guards. Tarnished silver clasps bind its edges, each adorned with a symbol that seems to shift and writhe when gazed upon, a reflection of the Abyssal Shadow's elusive nature. The title, embossed in a deep crimson hue, boldly proclaims in Aetern: "Codex of Corruption." As you run your fingers over the cover, the leather feels unnaturally cold, as if it's siphoning warmth from your very being. The pages, visible from the sides, are uneven, crafted from a material that's neither parchment nor paper, adding to the tome's otherworldly aura. Upon opening it, you're met with diagrams and illustrations of disturbing rituals, each more unsettling than the last. However, the script, written in a dark shade of midnight blue, remains indecipherable.
