RaptorExx is right about this being a potential lock due to short answers... We need reasons people!
Me, I've named quite a few lands. One of the privileges you get from having created your own worlds. To mention one, Menagah... That's a land full of hills and plains, a big forest in one end of the land, and it borders up to a chain of mountains in the other... The people living there have been peaceful for most of their existence, but war strikes the land... A racce is extinguished on the plains of Menagah...
As to why I named that particular land that particular name, I no longer remember. I think I just liked the sound.
