In my story the bad guy is named "The Dark Lord" (yes it's generic, it's humor-fantasy so it's just funnier that way). My main character calls everyone by a nickname, so he calls the bad guy D.L. But it looks weird when "D.L." is written like that, at least to me. It seems like it would almost be better as "DL" but I don't think that would be correct. I have an excerpt of dialog here, can someone tell me if I'm handling the nickname properly or if I should change it: He turned the headmaster to point out the door. “Out there the Dark Lord waits. I know, because I was doing the same thing there that I'm doing here. He's evil, he's powerful, and he's rich. Now, let me emphasize that last one. He's made a lot of good investments, mainly in pillaging hoards. You've heard how they raid the country side, the guy is making money hand over fist from that. He worked hard to get where he is. D.L. over there came from a slave pen, now look at him! I couldn't take that away from him. That would be cruel.” You'll probably find some other errors in this excerpt as well, I haven't rewritten this part yet So point out anything you feel like, but I'm really looking for opinions on how to handle this nickname.
