Agent Peregran told you he had high hopes in you. He asked you to do your best to ensure the Aetheric Field could be reactivated. Wizabo said a Protection Artefact was required to re-establish the Aetheric Field and protect Nosra. He requires Tower Fragments for the undertaking. While searching for Tower Fragments in Nosra, you ran into Elyos and relieved them of a secret document. You derived from the document that the Elyos had been tasked with invading Nosra and collecting Tower Fragments. Agent Peregran promised you that the Shadowbringers would take care of the Elyos and protect Nosra. He asked you to keep your attention on the mission with the wise man.
