When Arran Sensed the large cavern ahead, he came to an immediate halt.
While the creatures in the cavern were diggers, many were far larger than any of the ones he had encountered so far.
Within the mines, even the largest diggers were no more than eight feet from head to tail. But in the cavern, some of the creatures he Sensed were easily five times that size, if not larger.
Arran did not need to guess why he'd seen none of the larger creatures within the mines. There was no way they'd possibly fit through the narrow tunnel that connected the cavern to the mines.
And it was equally easy to see why, centuries earlier, the Darian soldiers had struggled to find the source of their problem. Dark and filled with cracks and crevices as the mines were, Body Refiners without Arran's Sense would have taken the tunnel for a dark corner even if they'd walked right past it.
