"They're dwarven... children," explains Midgrim to the human and the elf, whispering as if he could somehow disturb the sleeping statues if he talked too loud. "They didn't awaken right away. But sometimes they do. And then there's much rejoicing. We would take it ill if'n somebody robbed them of that chance."
'You understand me?' asks his straight gaze.
If they do he'll go take a peek into the narrow north passage. When he comes back to the others, he'll pass through the statues to see if there is anything but 'them' there and making sure they are all in good shape.
OOC: What lore, if any, does Midgrim know about the Stillborn, Imperialus? The Stillborn and kobolds? (I'm sort of surprised they haven't defaced or dismantled them, actually...)
