The Longdan (竜胆/龍蛋, Rindou, lit. Gentiana or Dragon Egg) is pyramid-shaped land-cruising mobile fortress controlled by the Chinese Federation, capable of deploying dozens of Gun-Ru Knightmares. It has two large cannons and thirteen normal cannons. Certain models are equipped with tank treads for land mobility, while others have hover systems to levitate across bodies of water.
