Valerius received a report that the flow of Aether had stopped near the Artefact at the Outpost Ruins, and he told you to investigate it. Lakaias gave you the details, and you went to check the situation. The upper part of the Artefact was gone completely, ripped from its base. You destroyed Caryatids near the Artefact and found evidence indicating that the Lepharist Revolutionaries were the culprits. You went back and reported to Valerius.
