When you become a ruler in Empire mode, be wary of the officer Diao Chan. Staying true to her namesake and Story mode, she has only one reason to enter your employ. When obtained, and a message stating, "Hearing of your deeds...." or something to that effect, "...Diao Chan decided to join you", dismiss her. She will steal some of your officers in this random event you cannot control or stop once in motion, saying "I can finally put my father's plan into action" or something similar, Note: If it instead states "Diao Chan entered your employ", the event most likely should not happen.
