Well, something cool happened last night that was botched by a remnant Markarth quest.
While traveling at night along the main path from Markarth way past the two bridges, farm, and mine that lead up to the city, I spotted a
just riding along the path. I followed him up to just before Salvius Farm, then he headed back and across the bridge near Kolskeggr Mine. I kept running out of stamina but was adamant to follow him, until I got caught in an auto-opened dialog with freakin' Brother Verulus, who I haven't seen since "The Taste of Death" was originally broken.
He kept following me around, and being that I've been trying to complete that quest since I first started it, finished out the dialog and tried to resume course, but Verulus kept following me and opening up a dialog. I eventually got away from him and ran to chase the
down, but I couldn't find him.
