Western Silvermoon City.

As a city on the border, besides typical defense infrastructure, at all the empty spaces there were also silver metallic walls built that were normally hidden underground and could be raised to a height of close to 10 meters in emergency situations. On top of these metallic walls, there were also laser-firing devices at one-meter intervals, which were driven together by the city's defense system and single Energy Crystals.

During times of war, these laser-firing devices would immediately be engaged to form a deadly laser net with a range of a few meters above the Energy wall, preventing all land organisms from entering the city.

Silvermoon City had met many attempts at infiltration by the rebellion — this line of defense had been successfully blocking the most threatening monster army of the rebellion's land troops. But clearly, any defense facility would only be able to defend against enemies from the outside.
