You should be fine. I may interrupt some of what happened but it won't change your post much, if at all. Also, I had a thought on the guardians.

What if they were originally created just to protect Pahn during his rest and scour the Earth for anything that may corrupt him or cause a disease of the mind. During this time they would naturally transition into protecting the Earth, assuming that as their duty upon his awakening in the third age. It just makes more sense to me since Pahn never really cared for Earth in the beginning so I doubt he'd make a force to protect it. I know this might not be a huge detail, but it was just bothering me a little ;D
