Tower defense [2]

The sun started to set, and darkness slowly enveloped the land. A cold breeze brushed through the forest; the paper-like sound of the leaves fluttering sounded across the area.

The scene was rather tranquil, but everyone standing on top of the northern tower, knew that this was the calm before the storm. 

Rustle—! 

Soon, the silence was broken by the rustling sounds of the vegetation in the distance. 

Stationed at the middle levels of the tower, I gazed into the distance. There were many black creatures in the distant forest, approaching our direction. Some were flying, whilst others weren't. 

The atmosphere was heavy, and everyone on the middle level of the tower started to take out their weapons, as they quickly got back to their post, readying themselves for the upcoming battle. 

"It's time we also get ready."
