Pauline Polaris is her alias, she tells the player, and her birth name is Jane Blud-Hagic-Maid. She changed it because she did not like it and because people were mean to her about it. The hint she gives players who must guess her birth name is as follows:
"'Change a letter from the word Dane to get my first name.
The first part of my surname rhymes with wood
The third part rhymes with spade
And the second rhymes with magic."
