Friday Fun! - Where did you get your Alias?

When my kids were young, we used to play this Dungeon and Dragons game. I was Robin of Rohan. "Rohan" is a region of Tolkein's Middle Earth. When I first bought a computer, my stepson was helping me with it since I knew nothing about it, and he set up that moniker, as a sort of joke, for other purposes, so I just kept using it.My real first name is Robin.
