There's a fantasy book series called DragonLance, and it was a big influence on my writing style. A character in the series spends all day writing the events of the world, while being pretty much completely cut off from the people he's writing about by his own choice. Before the round of last name changes took place here, I was reading the chapter where he's introduced, and took the name. It just seems to fit me the best.
If the name's taken on other sites, I just stick "ninja_" at the beginning. That came from a joke between a friend and me. I had found a user on another site using the name "pirate_asty", shared that with my friend, and she suggested I go by "ninja_asty". I used to call myself "speaker_astinus" though, because "speaker" is in reference not only to DragonLance but also my favorite book ever, Speaker For the Dead.
Obviously, I do a lot of reading!
