Teth is unique in Elden Nayor. Technically a possession of the Duchy of Niemarsh, it nonetheless claims identity as a separate fiefdom, and its independence is the subject of much political debate amongst the Houses.
Situated in the heart of the Nayoran Peninsula, south of the Queen (another point of distinction for Teth; all other southern lands are considered part of Ceres Nayor, and thus the dominion of House Lombardosian), Teth is a land of rolling hills and pastures, dotted with picturesque villages and family farms. The climate is ideal, and Tethian wines are perhaps chief among the many delicacies prized throughout the Peninsula.
That Teth, and its titular head, Nicolo Pebblebrook (who holds title "Earl of Teth" by popular acclaim; House Niemarsh, of course, refer to him as merely a "Regent"), are allowed such effrontery is largely due to the vast quantities of luxury goods they grow, manufacture, and ship throughout Elden Nayor.
It is also likely that Pebblebrook's own enormous personal charisma and effectiveness as an administrator are a decisive factor. Pebblebrook is unwed, and, despite any number of proposed brides, he has yet to commit to a marriage. Instead, he has deftly maneuvered his fiefdom into trade alliances with various Houses in order to strengthen the Tethian claim to independence.
In addition, Teth has instituted a policy of remitting to his lowborn a portion of the revenues from the products of their lands. Those nobles who accuse Pebblebrook of attempting to buy the affections of the lowborn with gold Kingsheads find their argument difficult; the controversial policy has, so far, been an unqualified success. Productivity has risen, and the average Tethian lowborn enjoys a standard of living considerably above his neighbors in any direction.
Thus, while House Pebblebrook currently exists only hypothetically (i.e., as a House without a clear line of succession or ties of marriage to other nobility), in the minds of the Tethian lowborn there are few men more admired, more deserving of the title "noble," in all of Elden Nayor.
