Again: the use of passages from the Encyclopedia Eorzea confirms in-universe sources. Specifically in-universe, present-day, Eorzean sources (although some of these may be Sharlayan at this stage). Saying that it should elaborate on the allies of Venat that sacrificed their lives with her would be akin to arguing that we should talk more about the individual servants of Egyptian pharoah Tutankhamun; not especially useful, and either very presumptuous or very difficult given we know very little about them.
