Sandstorm

Sometimes, a strong wind makes a sandstorm. The storm changes sand, stones and artifacts. The bells are ringing. You receive a letter about the danger in 30 minutes.

 

«In the next 30 minutes, the strongest Sand storm raves against sea and town. Goddess Seamoon has fallen into rage! Hear sound of ships bell? The storm will last one hour. Everybody will lose!  No one will survive.  All the artefacts and gold will disappear. Keep it in safe chest! We recommend you to leave game for this time.»
