Pen Names???

[Androxine Vortex]

I've been thinking about pen names for awhile now. I have never thought of using one but I'm trying to think if I HAD to use one, what might I use? What are some of yours? How and why did you select the letters you did? I'm sure they're not random and have some reason for doing so.

(I know that this next question is hypothetical and unlikely)
And let's say for example that a book gets really popular, and you write it under a pen name. If you make a public appearance, like an interview or something like that, would they address you by your pen name too? Just curious.

 

[The Grey Sage]

I considered actually using 'The Grey Sage' as a pen name but limited it to poetry only, as far a prose... I'm sticking with my real name.

 

[Arcturus]

If I ever use a pen name, I'd use my middle name or last name, but never my first. I don't know why, but I never liked how my name looked in writing. It also doesn't suit the type of genres I write with, so I'm not really that heartbroken over the fact.
