War is Inevitable

Boom.  A smell washed over the entire area.  The section of border wall lay crumbled as many dark figures started pouring in.  Patrols rushed to sound the alarm.  The sound managed to get through before being abruptly cut off.  The patrol fell to the ground, neck cut.  The enemy laughed as they rushed to the tree line.  'First stage: Complete!' 

News traveled quickly down the wall.  Troops rushed to engage the enemy, but by the time they arrived only the crumbled wall could be seen.  All signs of enemy troops had vanished.  The first priority of the troops was to seal the hole.  The only thing they could determine is some kind of chemical had caused the hole.

A lone messenger came to the capital to report the attack on the wall.  "So they have finally made their first move."  Eon clasped his hands together.  It felt like only yesterday that they had war with the Empire.  'They wouldn't attack again this soon.  Not at this time of year.'
