Thank you for giving us at least a section of the story a good end. I hope your health improves. If ever you write again I would write a smaller story to help negate lost motivation.
I don't like her trying to take the place of one of the others lovers, she should have just helped Claus beat the Bringer of the End, and left the others alone.
5 chapters on a mediocre love scene and barley a decent chapter on the elimination of a threat. I wish yiu would develop other aspects of your plot like you have before.
