uhhh why do i get a sense of foreboding, almost like this is just the beginning

It is indeed just the beginning. It's just like how they need to fix the inside happenings around mortia before they deal with the outside.(￣∇￣")

Basically the mortia became op that the empires noticed and are jealous of its influence and power ╮(￣▽￣)╭

The author is same author of the empress of another world. I don't think something big (bad) will happen since the other manhwa just run smooth thru the end

I do love how this author doesn't drag out the drama more than needed. She/he keeps the relationship and character development at the center as the leads handle the drama that does pop up like we wish every fictional character would in a story.
