[Morgeruat]

people main problem with him is also one of hid biggest strengths as a character, his attitude, he's brash, insulting, arrogant, headstrong and self assured, if you play the romance you get to see another side of him, and realise it's all a defense mechanism, he was abused by his father, his father refused to help sponsor him into the Order, but instead of giving up, and giving in to the pressure to quit he made his own way, by training himself (with help of course, but his allies are conveniently forgotten in his tales) to be a powerful fighter (lvl 7 is an extremely skilled and high level fighter in 99% of the forgotten realms) and then joined the priesthood, as a cleric of Helm(IIRC) letting his deeds earn him his position.

True he's a bastard to Keldorn when the elder knight is just trying to coach him along the right path, but he was refused by the Order because his father didn't buy him his way in, a perfectly understandable, if not easily forgiven response, Jan pushes the buttons of every character and so his ability to drive Annoyingman nuts is one of his finest moments, but he is despite his boorish attitude probably the best fleshed out NPC in the game
