Shadow Guards

Elder Gild brought Callon to Aethelwolf's office, while the elven people who came with them were taken to their temporary dwellings. 

Although Callon looked calm on the surface, he was actually feeling nervous deep in his heart. The moment they entered Barden Territory, he noticed the tall walls that surrounded the entire territory. It was made with magical stones that were almost unbreakable. The only way to destroy it was to use high-powered weapons like the magical cannons or magical artilleries. However, these weapons were hard to make and one would need the help of high-ranking Blacksmiths and Engravers to create them.
