Ruined Imperial Palace. Destroyed Royal Library.
The royal family at the ruined Imperial Palace were killing their way out from the forbidden area of the royal library. The scouts left by the erg race to investigate the location were silently killed by the grand duke and the crown prince. They made sure that these zergs would not be able to send any message even before they were killed. It's just that they didn't know that the way zerg call for help is different from humans who shout for help. They send some kind of soundless frequency to cry for help.
