I wanted Glimmer to have a mixed heritage, so she is wingless like her father but shares her mother's complexion. She is the hope of Brightmoon as she would be the first natural born member of the royal family that, like her mother, control the magic of Brightmoon.
I thought about placing the Red Knight in a tour of Blackmoor, the kingdom in which he appeared in his Filmation episode--but then I wondered who would care about a tour of Blackmoor? No one else of note appeared to be from there! Since we never learned his identity, I kind of went with the idea that the Red Knight was some how a mystical projection of Miccah. Possibly the Cosmic Enforcers or someone steps in to allow Miccah to help his people through TRK, or possibly Miccah himself has some latent magical abilities that he cannot fully tap into. Since I'm bringing back Angella's ties to Mizar, where her people are winged, I didn't think TRK could be her father (as some fans suggested) since he has no wings.
