Why do the scions have neck tattoos?

I'm curious whether there's any significance to the placement of them, for the characters that have them in other places. Is it just a visual thing (eg. it might look odd on Elezen) or is there an actual reason for it?

Urianger's tattoo is placed rather like the Duskwight cultural ones - I thought it was that initially.

The neck placement is most common, so that's probably the standard. For the others it's probably an aesthetic choice on their part, made out-of-universe so people will still notice it despite the neck being hidden or obscured. Urianger and Matoya have theirs on their cheek due to their necks being obscured (initially, in Urianger's case), while Louisoix and Rammbroes have them on their heads and white to make them stand out against their darker skin tones (both their necks are also somewhat obscured).

IIRC, Ejika (that pompous prick of a Lala in the Eureka questline) has 1 too, but it's on his back. Might be EE2 mentions it, I'll check when I'm home.
