NPC Brigade - Sir Gorn Halcos

Welcome to a new feature I just decided to institute: The NPC Brigade!

Every once in an irregular while, I'll post NPCs from my very ancient AD&D/Homebrew campaign, Alta. Just a note about some of the character rules in effect… Unearthed Arcana is allowed, for the most part (mostly weapon specialization and new spells). I also use(d) a form of Chaosium's Basic Role Playing rules for non-weapon proficiencies: Percentage chances to perform an action, skills go up through use, etc.

So, without any further ado…

Backstory: He is the bastard son of King Elidure Ceredigiawn of Ardudwy by a serving maid who died in childbirth. He knows of his parentage, although the king does not. By necessity a self-made man, after an early life on the streets he enlisted in and moved up the ranks of the city militia. He is an excellent horseman, and is often seen at the lists during tourneys. Generally good natured, Sir Gorn is also prone to occasional drinking bouts and fits of melancholy. He was a awarded a commot (an estate) consisting of 30 households due to his service to the city and the crown. His seat of residence is Paraveth Keep north of Dinas Powys.
