Okay, I caught up and I like it. I think you're being brave making up your own world. Well done! (although there are plenty things that are borrowed you could've made up yourself but I appreciate it's hard, if not impossible, to do something truly original with a chewed-up genre Fantasy basically is.)
However; there are some things I feel I need to point out.
Sometimes it feels a bit rushed. I would like to see more motives and explanation (and not just say he wants to become more powerful cause thats oversimplified imo). Why does Zalphon (who was keen on helping people some chapters earlier) want to be turned into something as awful as a Lich which is basically a walking coprse? A powerful one but still a corpse. Doesnt make sense imo. No good can come from that right?

A small nit here:
QUOTE
"Ravenblood, I thought I had killed you," Zalphon called out. "How do you still live?"
You jumped POV here. Everything else is written from Z's POV but now it jumped to third person POV.
One thing that kind of bothered me was the fight between Ravenlord ans Zalphon. It was over before it really started. If Ravenlord threw the match, I would've liked it if you had dropped a hint of why he would do that.
That battle should've been epic imo.
I hope it's some help, I am not trying to bring you down or be overly critical of your story. Which I enjoy btw!! Keep it up!
