Wind blew pass Herr Mountains ridges.
From the north to the south, small to big, the wind was whistling into the only valley in the mountains.
The valley was unnamed, but the fortress within wasn't.
Lightning Fortress!
The fortress was built completely with stone bricks as a defensive measure. It cost the royal family of Warren Kingdom a total of 30 years, and a tremendous amount of manpower and money to construct it.
Since it was in the middle of the valley, it acted as a barrier for Riverdale, the imperial city of Warren.
The fortress was impenetrable, with a total of 3,000 armed soldiers stationed here throughout the year. Even the enemies from the grass plains faced countless defeats before the fortress. Every disastrous defeat made the enemy retreat in a dejected manner.
The defensive abilities of Lightning Fortress made the people of Warren believe that it was impenetrable.
However, at that moment, Lightning Fortress was about to face its greatest enemy.
