Oh man. I completely forgot that bit. I was going to have Erandur suggest he tries the temple at Markarth and Dyce's response would have been along the lines of; "I can't really remember what happened the last time I visited, but they made it clear I wouldn't be welcome back." (You'd know he'd be up for Sam Guevenne's little challenge; probably did the Daedric Prince in the back of some cart somewhere along the way too.)
