Characters with this talent have a natural ability to see extremely well in the dark. The darkness should not be complete - such as at the bottom of a deep mineshaft or down a dungeon - but light sources giving the same level of illumination as starlight will allow the talent to operate.
Characters whose race has already conferred a standard Night Vision range upon them will have this extended by 2D6 yards. For Humans, who have no normal Night Vision, the score rolled will be the total Night Vision distance.
