Gabriel, when he sought to build great vessels of the sky, searched for his parts in the old, desolate city of Paritan, or so many would say.
But, however, my OCD cannot let this slide, as the city in question, the setting for Paritan Rumble and Labyrinth, is called Paritus, and not Paritan.
I call upon the official lore:
http://gunsoficarus.com/world/towns/paritus/As you can see, there is no dispute as to the official name of the city, so why would it be called "Paritan Rumble"
Well, the answer is that the word "Paritan" is an adjective referring to something "of Paritus", in the same vein of words as "english" or "cornish".
Just as you would call a rumble that took place in France a "French Rumble", a rumble taking place in Paritus would be a Paritan Rumble.
I'm sorry, but there are so many times I can control my pedanticism(?) after I see or hear people refer to the city wrongly.
