Heir to the throne of Thyzra. He's part of one of the few remaining powerful clans on Aion. Which is the feline clan. He's a calm and collected guy, doens't speak if he does not feel like it's going to bring him much gain. He's always occupied in his mind, figuring out problems his clan faces. He's considered an excellent heir to the throne and an example for his many brothers and sisters. He can be a bit stoic, but is also considered very mature for his age, not showing intense emotions easily. He says doing so will give any enemy the advantage in battle or political situations. If he smiles, it is genuine.

His name translates roughly to 'to stand tall'. As his mother wished for him to get throught he harsh state the world is in right now, the tumultuous world he was born in, she gave him a name she would hope bless him with the strength to take on the role to help guide the world to a better future.
