During the final sword fight Xander sustained an injury to three of his fingers from "The True Sword" however earlier in the film when Nikolai says "Blood upon his knuckles" there's a quick close up of Tias's hands, revealing the injury.
The cabin built by Ulysses was built by the actor who played him, Seth Easterbrook.
The "True Sword" was a "Hanwai Bastard Sword"
The idea for the film originally came about from an inside joke among the cast and crew during filming of "The Granary". This inside joke was then scripted into the film and quoted by Tias.
Although the prop for the 'pixie spirit' was only water, Seth Easterbrook was actually drunk during the entirety of the shooting.
