The story behind the Legend

[Apicius]

As all good spooks people here on the forum each have their own Legend (or username if you're being boring), but what's the story behind the name?
Some seem more obvious than others are more intriguing...

I thought this could be a chance to guess about the origins of some of the more interesting names (the more amusing suggestions the better!), share where your own Legend came from, or just say a bit about how you discovered SF or even Spooks itself.
