The moon is nothing like you expected. It is gray like you thought, but there is gray flora growing all over the place. There is something strange about the flowers. They are hearty and strong.

You leave the group, and follow your own way to the flowers. The place is not nearly as desolate as you expect. You see where the conjurer entered the castle. You remember its location, but you don't go there. 

You stay outside to admire the view. You see a large, hearty plant and walk up to it.  You study it, and decide whether or not you should study it more by getting closer.
