You give it some thought. Finally, you look up to Carly. "You called yourself 'Ciandra' before you took the shroom...did you remember that?"
Carly thinks. "It's strange...I don't know! It's like I was someone else but...I think I can read her memories."
Cody shrugs. "I guess we have our AAA map."
You look around. "All right. For all we know, we may also end up as elves, too. I could think of worse fates," you say. "But if Carly's been changed, maybe there's a way to change her back, or maybe we'll end up the same way. Either way, we need to look around and carry some of that mind-shroom stuff with us. We might not be able to retain what we are, but we should at least be able to hold on to WHO we are."
The three of you gather as much of the precious fungus as you can, Carly's access to "Ciandra's" memories and experience being a guide. Thus equipped, you set off into this new realm.
