Braska is a creation of Square Soft and is a motivation/background character in Final Fantasy X. As the man who will one day be High Summoner, and therefore Lord to my protagonist Auron, Braska plays a central role in Legendary Guardian. He is also a central protagonist in the stories Braska’s Journey and Bonds of Love.

Square does not give an official character description for Braska on their web site. However, after much investigation and research I have determined the following:

Male – Age 35 at time of his defeat of Sin. A priest of Yevon, Braska became a Summoner and resolved to Journey after his wife died in an attack by Sin. This woman, who in the game remains nameless, was of the Al Bhed race and therefore considered to be a “heathen.” As a result, Braska was largely shunned and his attempt to gain the Aeons and defeat Sin thought to be a joke. As a Summoner, Braska is a mage and has the ability to call Aeons to his defense in battle. Has one daughter, Yuna, age 7 at the time of his death.

Various conversations and recording spheres in the game give insight into the kind of man that Braska was. He, apparently, was a friend to Cid (the leader of the Al Bhed) and the woman he married was Cid’s sister. The two ran away together and Cid was furious over the event, straining his relationship with both the priest and the sister to the breaking point. The wife was attempting to repair the damaged relationship with her brother when Sin attacked the boat on which she traveled, killing everyone aboard.

Braska was a soft spoken man, prone to peacemaking, and apparently had a fun loving and congenial nature. He often laughs, even in sad or strained situations, and is constantly shown trying to smooth ruffled feathers between the characters of Auron and Jecht during their pilgrimage.

In attempting to create Braska for LG (and later for BJ and Bonds) I used the Kiersy Temperament Sorter. Braska is an INFP according to my interpretation. If you aren’t interested in checking out the full profile explanation, here’s a smattering of info:
INFP - The Idealist
INFPs, more than other iNtuitive Feeling types, are focused on making the world a better place for people. Their primary goal is to find out their meaning in life. What is their purpose? How can they best serve humanity in their lives? They are idealists and perfectionists, who drive themselves hard in their quest for achieving the goals they have identified for themselves
INFPs are highly intuitive about people. They rely heavily on their intuitions to guide them, and use their discoveries to constantly search for value in life. They are on a continuous mission to find the truth and meaning underlying things. Every encounter and every piece of knowledge gained gets sifted through the INFP's value system, and is evaluated to see if it has any potential to help the INFP define or refine their own path in life. The goal at the end of the path is always the same - the INFP is driven to help people and make the world a better place.
When it comes to the mundane details of life maintenance, INFPs are typically completely unaware of such things. They might go for long periods without noticing a stain on the carpet, but carefully and meticulously brush a speck of dust off of their project booklet.
INFPs do not like conflict, and go to great lengths to avoid it. If they must face it, they will always approach it from the perspective of their feelings. In conflict situations, INFPs place little importance on who is right and who is wrong. They focus on the way that the conflict makes them feel, and indeed don't really care whether or not they're right. They don't want to feel badly. This trait sometimes makes them appear irrational and illogical in conflict situations. On the other hand, INFPs make very good mediators, and are typically good at solving other people's conflicts, because they intuitively understand people's perspectives and feelings, and genuinely want to help them.
