So, Wanda Firebaugh is based on Audrey Hepburn. Or a reference to, or somesuch. I just noticed this! What first clued me in was her mount, Funnyface. Then I thought about her name--Firebaugh, Hepburn. I think there were some other parallels I noticed, but my brain is so cooked with the flu right now that I'm literally seeing things. (The flying wombat who visits me at such times tells me this is okay, but he's always been a bit shifty.)
