The Infiltration of Myridia was an event which took place during the Great War. The Grand Alliance sent Axikasha Keiran and a small group of heroes to the Aisonian capital Myridia to steal a powerful magic sword, Dawn, which was in the possession of Varalia Earthhaven. Although Ax managed to find the blade, she were spotted, and many of her companions died as a result while she and a few remaining heroes barely escaped from the city alive. The infiltration was immediately followed by the Second Battle of Myridia.
