Ancient Ruins

After passing through the dense jungle, the expedition team arrived at a hidden entrance concealed beneath trees, vines, and dead branches.

After clearing away the debris from the cave entrance, a thick metal door blocked the expedition team's path. Under the lights, specks of faint blue glimmered across its surface.

For example: the Control Bureau.
