Cinnamon the dragonborn!~ he's Vestia's boyfriend. he has two canons.
in DnD, he used to be a guardian drake that vestia managed to tame. following a dire blight affecting him, he managed to overcome it and evolved into a red dragonborn. he's stubborn but very protective of vestia, even though vestia is actually stronger than him :p

in Valician canon, he's a dragonborn from the planet Gaia. in that planet, Dragonborn were second only to true dragons, and they used to dominate the other humanoid races. following the destruction of the planet, very few of them remained, though their numbers grew across their time in Valicia.
Cinnamon was a dragonborn from ancient times, but a mysterious magic brought him to the present!~ this is how he met Vestia, and why he's dating her now.
