Build a large open Box PvP arena with a dark mushroom forest theme. The arena must be much bigger with a wide open flat sand floor in the center that is clearly visible from above. The surrounding walls should be low organic dark blackstone and deepslate hills not tall enclosed bunker walls. The red brown pillars with fire on top should be spaced evenly around the INSIDE edge of the arena rising above the terrain. The outer terrain slopes upward naturally covered in teal cyan foliage and purple pink moss. Scatter large blue teal and brown mushroom trees of varying heights around the outside and corners. The arena should feel like an open air stadium carved into a mushroom forest hillside. Top down view should show a large open sand center with organic edges.
