I'm guessing (and would suggest) that a couple of Eltos who are interested in what's behind the barrier -- perhaps, at least, the Palai trio that came with the group last barrierquest -- come up as well to try to utilize some of the bones' power. It might work a little better if someone's present who can manipulate the bones with the same kind of energy.

Also, thank you as always for your many organizational efforts around the barrier plot!
