So, Lil Headcanon here

Rosie technically has 2 names.

Her physical name, which is Rosie Jean Toulon.

This name is standard, doesn't have any special effects besides getting her attention.

Her second name.....

Is Her soul name.

Her soul name is Nybbas-ql-Paneu.

This name does have special effects. First off, if it's called, it will always catch Rosie's attention. This is very useful, because it will get her attention even if she's possessed by HATE or can't hear you. Second....it soothes her soul. When her soul name is called in its entirety, it has a calming effect, and this effect is doubled if it's called by a family member. Thirdly, her soul name being called will also temporarily break her free from any mental possessing affects on her. But of course....all of these can be used against her or be turned into a negative if her soul name gets into the wrong hands.

Also, you may have noticed something.

It's quite similar to 682's soul name, Atanti-ql-Paneu.

There's a reason for that.

Just like regular names, soul names have first, middle, and last names.

Soul names share the same middle and last if they are in the same family, which 682 and Rosie are.

Now, what happens to a soul name if someone gets married?

Well... it depends.

If the married couple love eachother, then one of the members of the marriage (typically the woman in a straight marriage, but in any other case, it's the younger partner) will take the middle ans last parts of their partner's soul name.

So yeah. That's soul names for you!
