Well the Soul Fragments are basically shrift abilities that are embedded (kind of literally) within an individual once they recieve a fragment. I think what people have been doing so far is giving people the Shrift abilities of former (now dead in the FC, we assume) abilities, such as I-the Iron for instance or Z-Za Zombie. But to create original abilities is completely fine as well, as we certaintly didn't see ALL the Shrifts that could have been out there. So far as I know, only humans (which would also include Quincy and Fullbringers, btw) can recieve fragments.

As to how significant they are? Well if you gather all the scattered fragments together you can do something powerful is what someone said somewhere I think, can't remember if that was reviving Yhwach or what, exactly. The second reason for why they're significant is because The Coven, aka, "the villains" are trying to extract all these fragments and collect them. So if you DO have a SF character... DUCK AND COVER. Jk, jk.

That being said this still needs to be discussed in context of the plot so...
