Very well told. I enjoyed the setting and the sudden turn of the fragile old man to demon/wizard.
I think Mostly Harmless’s idea of spawning two separate sequel paths is awesome, and hope someone with more skill and creativity than I takes that chance.
Thanks for the comments, everyone! When I wrote this, I didn’t really have any sort of idea for who the old man was; he existed merely to present the knight with his moral quandary. I like some of the interesting ideas that have been posed in the comments, though, and I hope that some of you will continue this.
