In Nivorum, IV's—used exclusively for select individuals and promising interns—are the most direct and pure method of introducing stardust into the body. The fluid contained within the IV is a scorching underground water, extracted through drilling from the dangerous aquifers hidden behind Nivorum’s stone walls. On its own, this liquid serves no purpose other than to cause pain; it must be combined with a special gas mined from the region, which allows it to carry and stabilize stardust particles. The gas prevents the dust from settling within the fluid, keeping it in constant motion. This allows the stardust, once it enters the bloodstream, to cross the Blood-Brain Barrier and reach the amygdala. Due to the risk of power intoxication—an uncontrollable surge of abilities caused by overdose—the IV must only be administered under expert supervision.
