She means the one directly south of the Lord oaks CS altar. It has a gold name "a pixie", all lower case, and is invulnerable. It responds to "Hello" and "Pixie" with something like "teehee, hello there" and "why yes, a pixie is what i am" respectively.
I dunno what else she responds to or why she is there. If I did know, I forgot. I forget things.... like my password here and which email i used to register it for almost a year.
