Atar is a Nord mercenary found within Sanuarach Mine in the town of Karthwasten. According to dialogue, he was hired by the Silver-Blood Family, and is stationed at Karthwasten when the Dragonborn first arrives there.
Atar is found arguing with Ainethach, who refuses to sell Sanuarach Mine to the Silver-Blood family. Atar claims that the Silver-Bloods so "generously" wanted to protect the mine from the Forsworn and, in this generosity, want Ainethach to sell it to them in order to pay for their services.
If the Dragonborn talks with Ainethach first, Atar will be inside the mine. He can be asked to leave, or the Dragonborn can tell him that he or she can convince Ainethach to sell the mine.
He will normally appear at the Silver-Blood Inn in Markarth after the dispute is solved (assuming he was not killed). However, he may not appear if Kolskeggr Mine has not been cleared yet, since his journey will be interrupted by the Forsworn there.
Ainethach "I want you sellswords out of my mine."
Atar "Watch your tongue, native. We'll leave when we're sure there are no Forsworn here."
Ainethach "Oh, and when would that be, I wonder? When I sell my land to the Silver-Bloods?"
Atar "The Silver-Bloods have made you a very generous offer for this pile of dirt. I suggest you take it."
- If The Elder Scrolls V: Dragonborn is installed, he might wear a full set of Nordic Carved Armor.
- If Ainethach dies before the miscellaneous quest is started, Atar and his men will simply leave, stating that their work is done.
