GURPS Lands of Legend
Earl Crassick Montombre holds the lands immediately south of Baron Aldreds fiefs. He bears the nickname “The Elfin Earl”, but there are several versions of the story of it’s origin: He’s really half-elven, it comes from his trading and dealings with the woodland folk or even that he’s a fey sorcerer operating in glamourous disguise.
He’s known for international connections, and it’s not uncommon to see eg. Mercanian folk in his lands.
And he is, of course, married to the niece of the King of Algandy (a powerful mainland nation), Thalia.
