Bone Boy answered Nalant's concerns.
And just as Nalant was about to ask exactly how many "many" was, the Rock-Eating Worms Bone Boy had mentioned began appearing on the plaza not far away.
He saw a great swarm of washbasin-sized Rock-Eating Worms surge like a tide, swiftly invading the base of that enormous stone pillar.
