I think there should be a comma before whether Christian or otherwise, and then a comma again after otherwise.

This is a little uncomfortable to read, maybe you could change the 'who have interesting stories' to 'that have interesting stories'?

Look at Dickens Henty or more recently in terms of historical authors Douglas Bond, most the characters in their novels are not the great historical characters of the world, but people living in great historical time
I think there should be a comma between the Dickens and the Henty, and after Douglas Bond I would put a semi colon.

A small low powered magic item might seem useless to great wizards such as Gandalf or Saruman but could turn the life of an entire village upside down.
I think you need a comma after Saruman here.

That’s because the thoughts which go through the mind of a soldier (survival, fear of the enemy, commitment to duty) are a lot closer to what we have experienced then the weight of responsibility which falls on the chosen one to defeat the dark lord.
I think you could do with a comma after experienced, and you mean than not then, I think.
