"Everyone, head into the shelters!" Re'Rak shouted, watching all the soldiers under him retreat into the wooden bunkers they had created. Once they entered them, they pulled in a rectangular vessel—that was filled with rainwater—over the bunkers. The Water Qi in it acted as a form of defence against the Kalhas.
Moreover, it prevented the Kalhas from sensing their presences. The Kalhas were sensitive to the presence of other creatures. Whenever a creature gazed at them, irrespective of the method employed, they would sense it and reverse trace it to the source. Moreover, they were able to transmit their attack through any means of perception. It was one of the reasons they were feared the most.
