Mekai volunteered to join the Xian Army as a signal corpsman. Her first and only assignment was to Pearl Station. While on duty there, Mekai accidentally transmitted a signal after the station's encryptor failed. That same day, the station was attacked, resulting in the loss of almost all hands. During evacuation, though, Mekai found that she had power over water chi when she put a crewmate into a crude stasis. At that time, she was subject to a vision of the previous Xian of Water, who confirmed her as his successor.
