Darth Mongoose is... a kind of regrettable thing left from when I was a teenager. It was around 2002, the internet was still pretty new and social media wasn't really a thing yet, so I hadn't really needed a username because there weren't a lot of sites that needed a login in those days. But then.... I discovered... The Star Wars website caption competition! (no, really...) They would put these funny out of context Star Wars images (usually production photos) and people would give them funny captions. Back in those days, this was really novel and cool and I wanted to join in, but I needed a unique username!
At that time, I regularly at weekends would go to a friend's house to play LAN games; stuff like Command & Conquer, or Baldur's Gate, and for whatever reason, when he decided to give me a player handle, he decided on Mongoose. It sort of suited somebody small and angry like me, so I went with it.
So what happens when you combine Mongoose with Star Wars? A username you get stuck with forever because nobody ever forgets "Darth Mongoose".
Funnily enough though, there is a small and cool story behind Kate Holden as my "creator/business name". See, Kate is what everyone has always called me. I've always been Kate, ever since I was a baby. But my actual full name is the rather grandiose Katherine Eleanor Felicity Holden. For a while, I thought people would take me more seriously as a creator, especially with the kind of posh nature of the UK's print publishing scene and my having an accent from the most working class town in Britain, if I went by "Katherine E F Holden" and had that on my business cards, book covers etc.
The person who told me not to do this, and to always just be Kate Holden was Judge Dredd artist Ron Smith. Sadly he died early last year, but he was an absolute legend and it was a privilege to talk to him and to see some of his original works because he was friends with my great aunt who lived near to him. He said, "Have a short name that's easy to say and easy to remember. That's why I've always been Ron Smith." So from then on, I always just went by Kate Holden (even though this means I've been frequently mixed up with an Australian novelist of the same name hahaha...)
