Collapse Of An Empire

--AN) More coming soon! --

*Boom!*

A loud explosion was heard at the entrance of the newly built dragonic city. "What was that!?" A dragonic guard yelled out as he rushed towards the entrance of the city, where smoke billowed up into the sky. 

The dragonic in the area were all rushing towards the same spot. Only those too young, too old, or pregnant went into hiding. As the dragonic guard reached the entrance, he was at a loss for words. Black scaled figures were pouring into the city by the thousands. He had no idea how they even got so close to the city in the first place without setting off any of the defensive alarms they had set up. Never mind the fact that they made it through the barrier that no one should be able to get through without the proper runic mark.
