Undefined Term: Soulkin (Contextless Usage)

[Anonymoose]

It's not that I feel "Soulkin" is improper grammar or incorrect terminology, but I would like to call attention to the fact that the term 'Soulkin,' is meaningless at this time and lacks contextual significance anywhere in the game, as far as I can tell.

I've searched out clues to no avail; this is all of the information I can find:

English: Soulkin
German: Arcane
French: Arcane
Japanese: Cursed

Context clues in the game: Spriggan are referred to as Soulkin twice and a coblyn is on the eluder icon.

Can we see some more clues in the game, or get a little background here?

The only thing I can see that coblyns and spriggans have in common is that they seem to derive their power from a silicon/crystalline substance, but that doesn't seem significant as it has nothing to do with souls, arcana, or being cursed.

Is it just like, an "Other Stuff" category?
