The Arixi Sisterhood by Pika-So
This Force-strong group of women had two primary objectives: (1) to teach and practice the healing arts; (2) to bear Force-strong children and disperse them throughout the galaxy. Over time, the symbol of their religious order evolved. It is said that this symbol is somehow permanently marked onto the body of every Arixi Sister and foundling. Based on Discovering Their Past and Children of the Arixi Sisterhood.
