Valkyrie

Valkyrie was an unreleased project from the Bella Sara company. Its exact date of creation is unknown, but images of conceptional art exists on Phil Trumbo's website, and the project has been confirmed by Trumbo himself.

Plot
The exact plot of Valkyrie is unknown as it never reached completion. However, according to Phil Trumbo the project was a spin-off fantasy story, featuring the main characters of Colm, Deru, and Emma fighting alongside their steeds. It was headed by Studio Voltz and Phil Trumbo, but never got farther than concept sketches.

It is possible that this project may have been intended to be a storybook project similar to the Storybook DVDs, or another full-length movie.
