Everything in the WOT books are written from an in-universe POV. There's no real inconsistencies, just different viewpoints and evolving arguments as new information comes to light.
I do realize that, but I reject that argument as it relates to most of the lore presented in those books. Not ALL of it is presented as physical codex entries written by some fictional person. Some of it is written as encyclopedic-style text that is supposed to contain factual information.
And really, what is the damn point of a lore book that is supposed to be a font of information if one can just use the "unreliable narrator" excuse to invalidate any of it, just like people do with the events of DA2? Frankly, I am continually baffled at why some people seem to happily accept that everything they read in these books is potentially inaccurate because the of manner in which it was written, which was a style decision on the part of its authors.
Some of it has to be true, and some of it has to be wrong or inconsistent, either with information presented in other materials, or the games themselves -- the primary source. They have even admitted mistakes themselves when they released the erratum for WoT Vol. 1 (re-published in Vol. 2). It's rather cute that they wrote this as having been written by Brother Genitivi, but it was still written by some Bioware person as a means of correcting errors found in the actual published book.
I bought the damn things, and will continue to buy them as they are released. Mistakes happen. I get that. But I'm not going to give Bioware a pass on all errors simply because some of them can be excused away by the style they chose to use.
