A small, translucent vial containing a shimmering, pale blue liquid that seems to glow faintly in the dark. The vial is made of delicate glass with intricate, gothic engravings depicting arcane symbols and eerie motifs. The liquid inside moves sluggishly, resembling thick dew, and emits a subtle, cold mist when agitated. The stopper is crafted from aged brass, featuring a small, ornate skull design that adds to the item's macabre aesthetic.
