I murdered one of the Thalmor guards at the Jarl's place in Markarth. Slit his throat. It was an act of hatred, I admit. After the murder the two other elves went searching, didn't see me and returned to pacing around as usual. I got no bounty on me.
Now, whenever they see me they attack, causing the humans to attack me as well. Guards and other citizens are not hostile and do not attack me if the elves do not first. The only thing that threw me off was that I entered Nepos' house (for Forsworn Conspiracy) and got attacked right away.
Question: Would it solve this problem to stay away from Markarth for several days? Or should I just murder the other two Altmer? Is there any other way to solve this, without loading a previous save? Because that one is kinda far back...
