An idea... dangerous as hell, but hey, it's a plan... but if I lose my psicrystal...
"I've got an idea." Charlotte says.
"I'm going to make an astral construct capable of flight. It should be about as small as Rallyn, so it should be able to fly through the tunnel with no problems*."
She looks up.
"That, though, won't be enough to tell us what's down there. So, I'll put my psicrystal on the construct, so that I can see what's down there through it. If there's nothing down there, the construct should dissipate after awhile and my psicrystal will drop and we can go get it, and then do the whole thing over."
"If there's something down there, then it might grab my psicrystal. But then, at least, we know where it is going."
But if the thing is smart enough - or stupid enough - to destroy my psicrystal... I don't think that it would be good...
"I think that this is a better plan than sending Rallyn alone down there. This way, we can figure out what's down there with a relative lack of danger to ourselves."
She looks around at the group.
"Well?"
*If it would have problems with flying down the tunnel, then tell me and I'll edit this post. AC I creates a Small construct, so it should be able to fit, but I'm just checking.
