Armor and machinery piled up into mountains one after another, even flattening the undulating mountainous terrain.
The fortress stretched for more than ten kilometers, built with high-temperature forged pyroclastic rock, and the surrounding slopes were planted with a mutated type of iron tree whose sharp branches and blade-like leaves added a thorny blade-like defense to the entire fortress.
