wickedwicker - Joanie's last name is Wicker. I was originally going to do something with witches, but I put Wicked and Wicker together in my head and was like "HEY IT WORKS." It combines her premade with her. Hooray.
dwagonslayer - This was kind of a joke in my head. I knew Diego needed something a little out there, and of course as an adventurer and tall tale teller he's all about slaying dragons and rescuing wenches and stuff. So originally he was going to be "dragonslayer," but that was taken. On a whim, I replaced the "r" with a "w" to see if that was open. It was. It made me laugh hysterically and that's the end of that.
sneakingaround - Archer's name is kind of a lazy one. There's a song by Theory of a Deadman called "Invisible Man," and though it isn't about the Invisible Man at all, it's pretty damn catchy. And the chorus has a line that goes "You've got me sneaking around like the Invisible Man." Thus, "sneakingaround" for Archer.
