These robes once belonged to Arca Jeth, an Arkanian Jedi Master who trained Ulic Qel-Droma, and who died during the Great Sith War. After Jeth's death, the robe was taken by Qel-Droma, who always carried it with him. From him, in turn, the robe came into possession of the Mandalorian scientist Antos Wyrick, who used Jeth's genetic material from the robe to raise Offshoot children, enhanced with Jeth's genome and Force-sensitivity. Wearing these robes bestowed an increase in wisdom upon the wearer, as well as an enhanced ability to refresh themselves within the Force.
