Depa Billaba, a Jedi Master, was known to wear the Lesser Mark of Illumination. Belonging to the Marks of Illumination, the Lesser Mark of Illumination signified membership within the Chalactan Adepts. Resembling the Greater Mark of Illumination in every aspect except size, it took the form of a petite golden sphere positioned between the eyes. This represented the seeker. It, along with the Greater Mark, symbolized the Adepts. Depa Billaba displayed both of these marks upon her brow.
