Sigrid Henderson, Stormfront, Smog, Velius Flynn, Shimmer, and Milo
The Night Riders is a traveling group of two Vikings and their dragons. Sigrid seeks to escape from her fiance, who pursues her and her dragon, while Flynn wants to learn more about life outside his secluded home and learn more about dragons.
Milo is a young Speed Stinger and Flynn's second dragon. He was originally the alpha of his own pack, but was deposed by a stronger and larger Speed Stinger.
The group was originally formed when Sigrid and Flynn first encountered each other in the woods. Though they were initially suspicious of each other, the pair eventually became traveling partners. Flynn helps Sigrid elude the Stormchasers that pursue her while she helps Flynn with his research.
