A small, vial-like container made of dark, translucent glass with a faint, eerie glow emanating from within. The glass is etched with intricate, swirling patterns that seem to pulse slightly when moved. The potion inside is a thick, viscous liquid with a deep purple hue, occasionally shimmering with streaks of black and red. The cork stopper is wrapped in aged leather, secured with a rusted metal band, giving it a post-apocalyptic, scavenged appearance.
