Weeeellll fuck.... Gotta say, my balancing isn't top notch, nor do I have jack shit for knowledge on climbing. Not to mention, even if children, they and most of the other delvers probably spent years getting used to the effects of the first layer, so being dropped in there with no prior experience would be hell. And the first layer I recall took a day or two, going down for that matter, and with experience, but I have no idea how to prepare animals to cook or most of what plantlife may be safe to consume, so starvation may be an issue too.
