Dim light, also known as shadows, refers to an area that is partially obscured by a faint Illumination.
Typically, this occurs along the boundary between a source of Bright Light, such as a torch, and the surrounding Pitch Black.
Other examples of Dim Light include the soft illumination during dawn and twilight, as well as the faint glow cast by a full moon.
However, it is important to note that in areas of Dim Light, such as those partially obscured by patchy fog or moderate foliage, creatures often have a harder time relying on their sense of sight. This can result in DIS to Attention Skill Rolls that rely heavily on visual perception.
