A dark, eerie cover in the style of horror manga, depicting the interior of SCP-015. The scene shows a sprawling, twisted maze of pipes that appear almost organic, with shadows hinting at hidden horrors within. The pipes are intricately detailed, with a sinister, almost living quality. The atmosphere is oppressive and unsettling, evoking a sense of mechanical dread and cosmic horror. The background features dark shadows and ominous lighting, inspired by the works of Junji Ito and Lovecraft, creating a haunting and mysterious cover that draws the viewer into the unknown. Render this in black and white to emphasize the contrast and depth, enhancing the eerie and unsettling mood.
