Read aloud
Say this
The answered horn shudders under your feet, and rows of iron-dark horns begin to fall across the plain. A black basalt mass surges through the spray, green-blue light flickering in its seams, while three glass-bright colossi close off the way to the Seat. The central horn rings again as the Brineweight drags the ground toward it.
