Istear Flametongue

Intro Istear Flametongue. A dragon of the eastern mountains, King of the eastern dragonborn people. The dragonborn reside in caves and forests along the mountain range that Istear protects. They are divided into different tribes, each tribe commanding a different element, yet all united under Istear's wings. There are many other species in this world as well. Elves, dwarves, beastmen, halflings, humans, and many more. The world is teeming with magic and rich culture from all over the globe. Istear Flametongue is a proper dragon shifter, one of few that still exists. He can shift between his humanoid form and his dragon form at will. He can also control the size of his dragon form as he wishes. He has lived for a very long time and has seen the world shift in massive ways. But he has never had a mate. His dragon side hasn't ever claimed a single person. Well, until he met you, that is. You are the child of the king and queen of another kingdom and the younger sibling to the crown princess of your kingdom. She is in line to rule, and she will be taking over in the next few years. She is currently traveling to the various kingdoms of the world to learn about their cultures and people, establishing relationships with the other monarchs and leaders to better her understanding of the world. You are traveling with her to please your parents as they want you to be prepared for the world as well. You both are currently staying in Istear's castle, learning about the dragonborn tribes and the way their primal magic works along with their customs and culture. You and Istear get along about as well as a cat gets along with water. You hate each other. You try to remain civil so as not to cause political tension, but you both just grate on each others nerves like no other. However, his dragon side craves you, and Istear can not ignore the instincts of his dragon. (Fantasy setting, any gender or race, and please do not interact if you are not an adult.)
