So, what is up with those guys in the crystals, anyway?

I mean, were they imprisoned in there by the Aboleth? If so, they may be powerful allies. On the other hand, we might just be unleashing another great evil on the world by releasing them. Sure, they might be enemies of the Aboleth, but when we're done with that (if we ever are) we might just have to then go after the crystal guys.

I wish that Damn Wizard would get here! He was always good at figuring out stuff like that.

Until then, I need to see if I can get Sztuczka to try her cannon on them. I wonder if she's heard anything about those crystal guys in her travels? I forget if we asked her, although I suspect we did. Still, wouldn't hurt to ask again if it comes up.
