My first name, and surname's first initial {ashleys}, then a number that is easy to type on the number pad and has a ring to it with my name {Ashleys165}.
Im a fan of the writer David Eddings and one of his characters Kheldar i thought was really cool. So i added another 'd' in there and came up with my name.
The guy on the right is Doug Remer (which I thought was spelled Reemer, because that's how it's pronounced :p) and I really liked the movie at the time, so I made a WoW character called Reemer, and after that it just stuck.
