I do not mean to change any facts, and am not sure where I am doing so. I am providing my observation and speculation.

and Keep in mind that, while the WoR does in fact acknowledge aura, and that having it is different from being able to utilize it, Salem fails to explain what causes it or how it works.

This is the omission which I was referring to.

In Grimm, they mention newer and more horrific forms without ever giving an example, and we were not told much of anything about what sort of study was performed.

It is minor, but it was an omission of details.
