Back storey would be along the lines that my character trained at the same temple/academy as the ebony warrior and has been sent to assassinate him by his/her superiors for reasons unknown. I was also thinking maybe a Stalhrim warrior with the same skill set from another temple/academy (back storey] still needs some work.
This play through would obviously require me to play on legendary which is something I havn't tried as yet otherwise trying to get to level 80 for the final showdown will require my character becoming a "jack of all trades" which rather defeats the object.
A warm up battle for the final showdown with Kastaag would be necessary and a good measure of how his skills are developing. Thoughts?
