Up, it's where I'm caught.
Finally read the chapters here, though it already seems as if you've moved onto the actual thing and out of development. I've gotta say that the first chapter had a strong feel of a manga story, the second chapter was a little different, but that's to be expected for a prologue type thing, though for the second chapter it seems a bit early, you probably changed that in the topic in Manga Creations, I'll find out later.
The idea is really original, though some things I've seen, how the hero in the beginning meets another with a gift or item believed to be rare or one of a kind, though those types of stories end pretty quickly or are discontinued, I believe this story will make it to the end after a long epic is told first. Where you go from the beginning is important, introducing a new character from the start was actually an interesting choice as the hero, Rex, was already experienced and knew his way around rifts and monsters, adding in a factor that changed him life completely is a good way to start this story. Adding in his experiences later on would be best, or having little bits of his memories shown in the beginning of each chapter as a short tale itself. Simply an idea I have though, I think you can handle this on your own, writing wise.
I have a pretty untrained eye so I usually correct grammar and spelling errors in my mind so my eyes ignore them and continue as if they were correct, so I can't give you much aid in that area, but I'll try to give my opinion on the story like above.
The story is good, so much to tell and so many questions, continue this, or at least let me read the other topic and I'll be sure to give you my thoughts on it then as well, I expect an exciting story.
