Ancient Cave

The map is set in a vast underground Ancient Cave with brown limestone walls. A slow-flowing river runs through the center, dimly lit by small openings above. Natural pillars of stalactites and stalagmites resemble ancient Greek columns. Hidden temples and crumbling statues of Greek gods lie deep within, with paths lit by flickering torches, creating a mysterious, sacred atmosphere.
