A dark and mystical background inspired by Black Sabbath, featuring a glowing pentagram surrounded by swirling mist and shadowy bats. In the starry night sky above, ominous rock formations and ancient ruins add to the eerie atmosphere. Mystical symbols and the Black Sabbath logo are subtly integrated into the scene, with hints of electric guitars and musical notes drifting through the mist. The color scheme includes deep blacks, purples, and silvery greys, evoking a brooding and atmospheric feel.
