He's the village priest. He acts like you'd expect a village priest from 1200 AD to act. Most of the catholicism is implied... I don't actually have a religion, there is no allegory. It's a very complicated world, and this seems to be the worst part. I spent a lot of time in my first draft skirting the issue and it shows. 
He's Morgon's foster father. He represents the forces of Love. He's the mentor character (who doesn't die, BTW.) I guess he could be a kind of druid character...

The Village priest, Father Matthew, took him under his wing. He took him back to his house and when the lad awoke he kept him there. Little by little he began to teach him. Herbs and medicine, religion and lore, history, geography, and anything else he knew. As Morgon learned he began to open up. As the years went by he became a quiet but confident young man, skilled and compassionate, but no learning could match the magic in his ever-changing eyes. Morgon and Father Matthew grew very close in those years; rare it was that one was seen without the other.
