Ok: the dragon is Silic, he is best known for having very little consideration of others, often believing he is superior to people without even getting to know them.
He's incredibly successful so despite his personality, he has a lot of "friends" in high places, but he never let's himself get too confident; he's always got a backup plan
his one weakness is...you guessed it...food
(hopefully this character isn't too much of a mary sue
)
