Occasionally a naturally formed Self will grow tired of living without a body and will fly away from its cluster to merge with a consenting individual.
Each self bares a unique set of attributes that may be merged with the individual who chooses to wear it. When a Self is worn, two become one as the qualities of the individual and the Self combine. Alternatively a Self may simply cover up the natural qualities of one’s personality and sometimes the qualities of the self will entirely overpower that of the individual who wears it, particularly if that individual holds few traits of their own.
