Sarpedon

To be fair, he didn't actually 'name' them. He merely identified them; i.e. 'that Earl,' instead of Jakben Imbel.

To what author is the mission revolving around the town of Hackdirt an homage to?

I hated that even if you figured out that you were getting the wrong orders, you couldn't really do anything. If you look closely in the boxing khajit's house, you can find his friggin black hand robe.

Its one of several things in vanilla oblivion that the developers put in for flavor. There's only a couple of subtle clues, and no related quest. Apparently, there are several little marital infidelities going on.

I find it weird how cold married couples are to each other in Cyrodil. Is nobody happily married? Husband: "Hi there." (not, 'Hi honey!') Wife: "Its YOU....hi." ('how was your day, darling?') Husband: "I ran into some goblins the other day, nasty creatures." Wife: "Stop talking!" And then when that Athram guy in the imperial city turns out to be a Mythic Dawn assassin, and tries to kill you, only to be cut down by a dozen guards, (seriously, why do the mythic dawn agents attack you on the street in broad daylight?) his wife treats you like nothing happened. She isn't resentful, or apologetic, or shocked, or anything.

I'll guess 5 people. two women and three men. Who's wife is having an affair with the blacksmith's assistant?
