Agnis is an old woman living inside Fort Greymoor and who cooks and cleans for the occupants, which are Legionnaires, Stormcloaks, or bandits, depending on the state of the Civil War.
She is not hostile to the
Dragonborn and when spoken to, she says that she will never leave the fort, and has been the maid for all the different factions and groups who have inhabited it. They come and go so fast, she doesn't seem to care. She tells any new group claiming the fort that she comes with it.
She is the target of this
Dark Brotherhood assassination contract given by Nazir. One must kill Agnis for a reward of 500 - 700 .
"I can't even keep track of all the people who have been in and out of this fort. They come, they go. I barely notice."
"I remember one morning long time ago, I woke up and the place was run by some Orcs. Went to bed that night, it was all vampires. Don't matter to me."
In the note, Soldier's Request, it is mentioned that Agnis prevents the soldiers from sleeping.
Agnis wrote a Complaint Letter to the soldiers, which can be found in the chapel on the uppermost level of the fort.
