@Pasta;
When I was making a headband, I actually considered using the Omega sign, but decided against it due to cultural difference. It's the same with the Arabic symbol. I considered a few other symbols as well, but it all made the same cultural cliff. The symbol I have now is a bit, well, futuristic, but, yeah...
I also considered simply making a dot on the hetai-ate, or a Full Stop as the name actually is in english (weird). The reason for that train of thought was the fact that Gobi is actually a term used for the end of a sentence, but is also used as a way to say "The End" for various things, such as a blind road, the end of a movie and stuff like that.

*googling*
Yup, it is ^_^
I really couldn't remember the name of the place, I just remembered how beautiful it was :p

I added "The Trainquil Spring" to a hider in the OP called "Character Hideouts/Special Places".
For Daiken's Trainquild Spring, I found this image

Is that all right, or will I need to search for another?
