According to Canix, the Sauro War Depot Researcher must know something important, so he asked you to kill him and obtain usable information. Following Giriltia's instructions, you killed the War Depot Researcher and brought back the sketch of the Ancient Weapon. Canix though that it was an Ancient Weapon Prototype, powered by Idgel. He also said that the notes reveal that the 40th Brigade General Sita found pure Id in the Sauro War Depot and keeps a Shugo Researcher prisoner to research the Id and the Ancient Weapon.
