Marius Caro

Count Marius Caro is the Count of Leyawiin. He is married to Countess Alessia Caro, daughter of Countess Arriana Valga of Chorrol. For 7000 gold, he will sell you a house in town. After you complete Mazoga the Orc and Knights of the White Stallion quests, he will make you an honorary Knight-Errant yourself, and thereafter you can collect a reward of 100 gold each from him for bringing Black Bows.

During Allies for Bruma, you can ask him for help. If the Oblivion Gate outside of the city is still open, he won't help you: When the gate is closed, however, he will help out:

He wears a black & burgundy outfit with gold trimmed shoes, and a leveled piece of jewelry. He also has a sizable amount of gold, keys to the castle, and a key to the Secret Room.

Quotes

 * "Leyawiin is beset by enemies. The Empire does nothing to help us. Even before this crisis, I did not have enough men to patrol my borders. Now, daedra are pouring out of an Oblivion Gate on our very doorstep! No, I don't have any men to spare. Bruma will have to look to its own defense." (Before closing Oblivion Gate outside Leyawiin)
 * "Well, with the Oblivion Gate near Leyawiin closed, I suppose the immediate threat is lessened. I will do as you ask. Let no one say Leyawiin did not do its part to uphold the Empire." (After closing Oblivion Gate outside Leyawiin)
