Armadons stage is the Hollows. The Hollows is a mountain cave in which Armadon stayed in until the cataclysms caused him to be aware of the other Dino-Gods and make him leave the Hollows in order to stop them from destroying the land. in the background their is a giant pillar of rock which is like a support beam and their are small little caves like rooms and ladders in which allow the humans under Armadons control to stay with him. On the left side their is a spike ball like structure and a cave entrance looking like a gaping mouth with sharp teeth. On the right side their is a spike pillar like structure.
