Well...
Coiled Dragon does have a Western/European feel to it.
The description of some characters are like Europeans.
Some of the story plot-lines have Western mythological elements.
It struck me that the beginning have strong King Arthur Pendragon/Merlin/Western Magecraft influence.
I still would prefer using pinyin for the names... but Western/European names would work just fine.
I think translator preference and comfort zone should be the determining factor here.
