The wiki lists some geographical features, the so-called "Major Geographical Features". But who named them?
If you mean the ones posted on the wiki, well, that would be me.
Why?
Another player (who no longer plays) and I were talking one day and decided it would be fun to do. So we looked around, asked some people what they thought, discovered that there really weren't any that people used, so we made them up. Admittedly, we weren't that creative with most of it. A few more have since been added by a few other people. (And no, I did
not name the Astrum Woods on EC...)
