Grizelda is a substitute barmaid in the Inn. If, as a male player, you try to flirt and find yourself with a hand full of cellulite, you have gotten Grizelda. She only comes in to work when Violet has married another male player. Grizelda will work the bar counter until Violet divorces him. Which she will.
In the meantime, no male players in the realm can benefit from flirting. This can be exceptionally inconvenient right after a dragon kill. As soon as Violet divorces her husband, Grizelda thankfully vanishes.
