Novablood is a Protoss drug used to supplement their forces in areas without starlight. Derived from an Aiur plant capable of storing tremendous amounts of light energy, the substance can sustain users for over long periods of time. Forced into a nomadic-like existence, many protoss have taken to using Novablood while rebuilding their forces in secret. Applied to the skin, users feel an immediate rush of power that can last for days depending on the amount used.
