By expending a small quantity of sapphire, the immortal can affect affect the light level of a given area he or she can see, limited to the light in a single zone. This ability dim a brightly-lit area to dim lighting, or dim lighting to complete darkness; alternatively, it can raise the light level accordingly. This light has no discernible source, and shadows are only cast from previously-existing light sources. Maintaining the adjusted light level requires moderate concentration: if he or she wishes to attempt an action requiring a die roll during a turn in which she also wishes to maintain the adjusted light level, she must successfully roll a Good (+3) result on the Immortal skill after completing that action. Failure indicates that the light level returns to normal.
