Coming from tumblr....I saw that just there.
I haven't read this spin off past second chapter. Will catch up now lol. I am surprised Variationa didn't mentioned my name!!. To tell the truth I am behind all of that mess of Rodonaito/Rhodonite/Lord Knight/Road Knight. lol Variationa is so kind. >_< Too bad it took 6 chapters to knew the official one.
So you knew Road Knight means drug all along?. Why didn't you said it to me?. That would have avoided all the mess happened in tumblr. _-_
I didn't know it would refer to a drug. I thought it would refer to Gajeel, like a knight alone on the road. Lord Knight by default never made any sense as you're saying two titles at the same time. Or it's a knight or a lord, but not Lord Knight. Rhodonite then didn't refer to anything. It was of course possible that something in the story called Rhodonite would be important, but the reality is that something completely made up does not work well as a title. Also Rhodonite really sounds like how a Japanese person would say Road Knight.
So the only logical conclusion was that Road Knight would have been the correct one.
