I'm just going to say that Nomad is an unadulterated mess. Look at line 164 in the Nomad_split_006.xhtml file. Paragraphs filled with RLM characters (why are they adding strong R to L on what is basically English text? Zero width joiners everywhere, paragraphs ended by pair of <br class="whatever">, use of strike which has been deprecated for ePub though the calibre class using line-through is correct. Not to mention in the stylesheet, calibre9 uses text-align: LEFT; which is incorrect since that should be text-align: left; (case sensitivity, you know).

As for Blood Oaths? It has more than enough errors in the .opf file that I didn't bother doing more than a cursory glance at the rest of the file.
