Minyan Underground Chamber

Green Cavern

The cave is a rough-hewn chamber within the Minyans' subterranean network, its walls jagged from natural collapse and rough labor. Dust and rock particles hang thick in the air, clinging to skin and clothes, while the flickering glow of distant work-lights casts long shadows across the uneven floor. The space feels both confined and cavernous—large enough to hold dozens of Trogs and outsiders, but pressing in when the rock groans under pressure. Damp stone smells of old earth and crushed minerals, carrying whispers of machinery and voices. The ceiling lowers dangerously in places, where recent tremors have sent loose rock pattering down, forcing characters to move carefully or risk another collapse. This is a place where plans hinge on every step, where the ground itself seems to breathe against them.
