Well, I guess sometimes you just gotta give things their time. It can be annoying when you’re reading a story and then suddenly have to go through 10+ chapters until you find out what happens next. It’s annoying, but so far, whenever I decided to give these other POVs a chance, I almost always ended up enjoying them. Like I’ll start off just skimming through the chapter and suddenly I’m intrigued and start reading slowly instead. Really, the only exceptions so far have been Toren(kinda) and most of the Goblin chapters.
I still remember seeing the next 7 chapters being all some Wistram flashback—I was so annoyed… but in the end it actually became my favourite side story!

What I’m trying to say is… well, nothing. Sorry, this is basically just a beacon for myself to remember where and when I started my journey again.

For a second Umina thought the Dullahans would turn around and throw their drinks at him. But then just got up and left.

The second part is a sentence fragment, the sentences should be joined with a comma.

drinks at him, but then just got up and left.

“What the great treasure that the Forgotten Wing company had been founded on.”

–> What the great treasure that the Forgotten Wing company had been founded on was.

“The smallest people in the world; only a foot tall.”

-> ; only half a foot tall.

“Erin and Ryoka and those from her world knew of school as a part of life, but in other places, school wasn’t such a basic pillar of existence.”

-> Erin and Ryoka and those from their world

Will was fully dressed -> Wil

And Venaz … well, he was dressed, but somehow, the bare-chested Minotaur seemed as fitting as clothing for him.
-> um … ouch. Too many commas, too clunky – I get what you’re trying to say, but I’m not sure that sentence can be saved.
Maybe: “And Venaz … well, he was partially dressed and for him, being bare-chested seemed as fitting as the finest clothing.”

And as someone else mentioned, fourteen is too small a number to approximate in that context.
“Just under one miilllion” is fine, because it’s a pain to type out (and read) “nine hundred and ninety eight thousand, seven hundred and sixty three.”
But it’s much easier to just say twelve or thirteen … there’s no reason to say “just under fourteen of them.”
