First things first, Eva had Luxia stop their joyride as the Light Phoenix blazed through the atmosphere, reaching the Aether Hall of Vita City-State in two instants. Eva had no idea where they had been before, but for it to take more than one instant at the speed of light meant that they must have been many continents away.
She jumped off Luxia's back and used her Short Blink skill when she was close to the ground in order to land safely. This technique was commonly used by players with flying mounts allowing them to enter combat quickly and was especially deadly when performed by rogue players in combination with their cloaking skill.
Eva entered the Aether Hall after being greeted by Vitae, heading down to the former basement which was now housing the Anomaly Realm. Only she knew what she did down there, as she had spent less than two hours before she came back out.
