Pernos said that a special weapon would be useful to compensate for your lost abilities. He pointed you to Sanctum, to seek out Anusis. When you asked Anusis for help, he ordered you to get special materials from the ship Steel Rake, Dark Poeta and Theobomos Lab and take them to Baoninerk of the Tigraki Workshop. When you had all the materials, Baoninerk made the Sword of Transcendence for you. Pernos said you'd taken the first step to recovering your memories.
