In this instance I have to say I can't really answer this in-depth because I'm not sure yet how her travels went in this period. It's not something I wouldn't expand upon later, but this is something I'd like to take time to think on. I like to keep certain aspects of my characters background vague so I have the ability to add or remove things(with the consent of the GM, of course) when I feel it's needed. What I can say is that she probably didn't go to too many places before Gobi, maybe one or two, and didn't stay very long. The where and why will not be finished by the deadline, however, as I want to think about this section in-depth and at my own pace.[/quote]

After discussing this for quite a while we've come to the conclusion that it would be better if the character was either born in Gobi a few month after the mother arrived there, or outside it and then moved to Gobi after a while. 
The reason is simply that a pregnancy is a big deal for a woman, and even "easier" pregnancies will come with a lot of problems that will make many types of travelling hard. Even after birth the mother isn't really free to move around too much as she now has a baby to care for that needs food several times a day and lots of irregular sleep, meaning that the mother will be a zombie for a while and depending on food (not sleep) to keep her strength. An adult (pregnant) woman would surely know about this, and would probably look for a safe place to hunker down in for a few months as soon as she was banished from the clan.

Engraving's aren't the Kajiya sealing technique, that would be apply seals during the process of the forging, which is a rather involved and taxing process, especially if there is only a single smith working on a work. The seals are embedded into the metal by use of chakra and chakra alone(as one can't write or engrave a seal onto a piece of molten slag) hence why there are no real outward signs of sealing on the blades. As for the Fuinjutsu aspect, I kind of see it as the ability to control chakra and command it, though this view has been shaped by other uses of sigil-based systems. When I think of a seal, I think of it as a series of commands to the chakra inside of it, telling it what to do and what not. Thus, while the most obvious way of using it would be the ways mentioned, I don't think that too far-fetched to do thinks like, say, have the chakra inside of the blade convert the iron in blood into metal or give advance control over lightning chakra or other such things. Also, I can think of one way that fuinjutsu is used offensively that I would believe supports this theory: Explosive tags. Those are definitely fuinjutsu, but hey don't protect, restrict, capture, or absorb anything. What they do is explode, and that means the seal on the tag is telling the charka within it to surge outward in an explosive fashion. I know it's only one, but I think it's enough to go on at least. 

Now, for the engraving, it's basically the same as regular sealing, but short-hand(due to the lack of space) meaning the weapon would only be able to do one thing, and the thing would have to be simple. Plus, there were the problems mentioned above about this method and the method of painting the seal directly onto the weapon.

After a fierce battle, won by reason, we have decided that the most reasonable way of looking at the whole sealing-business is to view fuuinjutsu as a very generic term that encompass almost all use of "chakra writing". From summoning scrolls to Yondaime's special kunai to explosive tags and beyond. 
We also talked about two standardized ways of using fuuinjutsu on weapons. 
One is demonstrated by the fourth Hokage and his special kunai which allows him to use his teleport with the kunai as a target. The seal is written (or engraved or whatever) on the weapon, visible but unreadable to someone who doesn't know chakra writing.
The other is demonstrated by summoning scrolls. The writing is done on a surface which the weapon is then placed on. As the seals are "activated" they do their stuff on the weapon, whatever effect this may be. This should not leave a mark on the weapon, but the effect will be there.
