Nothing is known about Maybell's background.
Maybell can most often be found in Armadillo, where she works as a prostitute at the saloon. However, she can also be found working her trade or engaging in a game of blackjack in Blackwater and Thieves' Landing. She is the only prostitute that gets kidnapped in Thieves' Landing. Other ladies of Thieves Landing may get kidnapped, but Maybell is the only prostitute.
In undead nightmare she can be found as a fresh undead saving towns throughout new Austin. And some times in the woods coming out of thieves landing.
