Mine is named after a hamster an ex-girlfriend got me. He was named for Logain, an important character in the Wheel of Time series. At the time , I had a friend who hated all things 13375p34k, so I altered it. This confused the ex-girlfriend. And a great many other people.
The hamster name became an email address, and then a username on GITP, and then on here when a friend brought me in for a game.
