Name: Alton 'Longjustice' Frey; Master of Laws
Biography: Alton Frey happened to be one of many uncles from the House of Frey - having spent his earlier years helping his five brothers manage and run the Twins, writing up laws and rules that helped increase the livelihood of both those crossing their bridge and the smallfolk in their lands.
Alton Frey was a deep man of honor and the law - taking things on some occasions literally. Holding both his brothers and their families to a high standard, in order to improve their lot in Westeros. Not to mention, with House Frey as large as always - rules and boundaries helped keep everyone from going after each other.
Sadly the relationship of Alton and his brothers wouldn't last - as the son of one, was caught pillaging one villager' hut during a drunken rampage. Instead of excusing and paying for his crime, Alton instead decreed they be hanged or 'take the black'. This ended up alienating him from House Frey entirely - since while he wasn't head of the House, he did cause enough trouble among the smallfolk when he informed them of small details and whom might be responsible. In the end, Alton got his way - while also being banished from his home for being a 'rat'.
Granted Alton' reply at such a situation was to call them all 'rats whom ate other rats'. Alton spent most of his time as always, travelling the lands as a hedge knight, and upholding justice. Keeping the King' Road clear of brigands and bandits - utilizing his longbow, often claiming to be 'the best bowman in the Seven Kingdoms'.
During one such incursions he encountered the 'Wise King' Jaeharys I Targaryen during one of his many visits in the Two Crowns Inn. Here he would befriend the wise and just King - five years later, he would once more meet the King, when he was asked to fill the post as Master of Laws. Due to in part the last one dying, and his growing reputation for upholding law and order in the Riverlands - a man of virtue and honor.
For the time being he has held the post for almost twenty-seven years.
