Nenya

 is an Altmer and the personal steward of Siddgeir, Jarl of Falkreath. She lives in the Jarl's Longhouse.

Before that she was also the steward of the former Jarl, Dengeir Of Stuhn. Unlike other members of her race, the Altmer, she is much less "snobby" to the Dragonborn and far less rude.

Lakeview Manor
The Dragonborn can purchase a plot of land located at Lakeview Manor from Nenya for 5,000, upon completing certain quests for the Jarl of Falkreath.

Trivia
