Isolated as a young child Argon tends to keep to himself, not usually opening up about things and especially not sharing important information to strangers (He can be quite persuasive when he wants to be though).
He grew interest in other languages due to all of the studies (reason for Gift of tongues Racial Trait)
During his studies he ran across draconic reading that talked of creator of all. Curious about where his 'friend' the eidolon might have come from he read into it. It is his belief that the eidolon was given to him to aid in his goal by Apsu himself (Although false.. it was what he accepted as a child)
Being for the most part still new to the outside travels (and also being a gnome) he can be very excitable, simple things throwing him into awe.. such as the sea, since he has never traveled there. Most things he has only read from books, leaving him only to his imagination. Many things are still new to him.
If someone seems irritated he usually does not back down, instead prodding the person just to see what they do. He rather enjoys getting reactions out of people. (A reason for dabbling in Alchemy ^^)
