Velius Flynn, commonly referred to as Flynn is a Viking boy and born to a rather small tribe called The Tinkerers, who were largely wiped out during a pillage on their main homeland and were forced to move to a much smaller location with reduced numbers. He bonded with Shimmer after a chance encounter with her, leading to the two bonding over time and becoming Velius's dragon mount. The pair explore the world in hope of finding critical advancements to help his people rebuild their society. During his journey, he met Sigrid Henderson and helped her escape from her tribe, the Stormchasers, who were pursuing her. She stayed with him and they became traveling partners and eventually married.
Velius is a very sturdy boy with short black hair, he wears a dark grey hooded tunic and a brown cloak. He has a crossbow strapped on his back along with bolts that are strapped to a large brown belt around his waist. He also has a research book, dagger and slingshot attached to it. In addition, he wears brown pants and boots along with black gloves. His cloak has Changewing scales sewn onto it, allowing it to camouflage with Shimmer but only if the cloak is touching Shimmer's body.
Velius is very intelligent and curious about the natural world. His upbringing within the Tinkerer clan has made him very resourceful and creative, allowing him to make inventions out of the most simplistic of items. He is very serious when it comes to his work, especially saving his people but can also easily relax if its needed.
