Craving for conquest is in Krogan's blood. In the southern lands their deadly army has been active for several decades, but their warriors didn't master the art of war. Insufficiency of intellect doesn't let Krogans reach the level of training of Human or Magmar warriors, that is why the monsters never tried to conquer neither  Orgiy, nor  Khair. 

Warriors of Faeo! Krogans were able to lay the course to the shores of Ogriy and  Khair, and ships with furious invaders are sailing to the distant borders of the continents. Sentries are not leaving their posts day and night in the city ports, waiting for the enemies. They need the help of the brave warriors in order to fight Krogans back! 

If you are ready to push the invaders back, go to  Sentry Requt at Grand Fort Harbor and  Sentry Groumer at Terror Wharf to start a new quest.
