Don't worry, I will keep it safe.
Connal is generally a happy individual, always glad to make friends. He is very secretive about his life though, and rarely spends time with anyone outside of school. Despite this, his friends find him trustworthy. He looks at secrets as any Griffin would look at their treasure, and once is told not to tell anyone, he will never speak of it again. He has often been made fun of for how seriously he guards the most menial of things -such as a soda- when a friend asks him to watch it while they are gone by refusing to move or look away until the owner returns no matter what else is going on around him. But he has little choice over the matter, even without his father's constant lecturing, his genetics would make him act the same.
He is also has strong faith in the Christian God due to his family's close history with the Church.
He also always keeps a Claymore Sword hidden with magic on his person at all times, As well as a bag of runes carved on pebbles for miscellaneous uses, and a magic book that has been passed down in his family for generations that specifically teaches the Art of being a Guardian.
"Griffins have always been the perfect guardians. If something needs to be protected, no matter what its value size, or form is, a Griffin will guard it with its life." This is what Connal grew up hearing. Never a day went by without his father drilling this ideology into his head. His father also taught him what he needed to know in order to protect anything. "A Griffin may be required to lay down its life, but that must be considered a last resort. For when you die, you have failed." He was taught how to fight, how to use magic, how to hide, how to find, and much more. His father was not a harsh man, but he was very strict. He was considered to be one of the greatest of guardians, and wanted his son to be even better than he. Connal grew up never knowing his mother, although his father rarely spoke of her. All Connal knows is that she died giving birth to him.
Note: So I looked up the Griffin's place in mythology, and was surprised at what I found. although the comparison was never made, after looking at a few different sources, it seems as though the Griffin is a lot like the Western version of the Nine Tailed Fox in Japan. They play very different roles, but it seems like the power of each one is very similar. Kind of interesting when you look into it. Sorry, I normally don't add notes like this to the bottom of my character sheets, but I found the mythology fascinating.
