UO Second Age

I remember a grey npc paladin spawning outside of Delucia with the other paladins. The paladin’s name was “A Paladin”. I can’t remember if it was Blue, but I know it would attack a player on-site and turn grey. It was like fighting a blade spirit without the poison. The gains were great, especially for parry. I think it spawned only once or twice a week or it’s possible someone else was sparring with it. Any ideas?
