So I'm sure some of you have found http://www.uesp.net/wiki/Skyrim:Brand-Shei in Riften, the dark elf with the strange name. He explains how he was raised by an Argonian family who found him as a baby wrapped in some sort of Telvanni cloth (I wish I had some exact reference which may be helpful to TIL if they haven't found it already). He says he was looking for clues about his past.
Don't know how many people have stumbled upon the shipwreck of The Pride of Tel Vos (this is a little ways Northeast-East of Winterhold, about two islands out), where you can find his mothers journal. In it, she talks first about how she was looking for young Brand-Shei, and then describes the "Fall of House Telvanni," where she was in the basemant as Argonians stormed some sort of Telvanni town. She gave the baby, who is now Brand-Shei, some sort of name which I forget, and as a final note states that he is the last living heir to House Telvanni. This was heart-rending for me, but ever since the Thalmor came along I'm starting to see the true face of the mer.
Now, most of you ignored that and joined the thieves guild, which involves an initiation quest where you are to steal a ring and place it in Brand-Shei's pockets. The goal of this quest is to put Brand-Shei out of business. The guards follow suit and arrest him shortly after the quest is completed.
Really? You're going to grab the hearts of all Dunmeri sympathizers with this innocent trader who is the last living heir to House Telvanni and crush them by throwing him in jail? I know the plan was to "take Morrowind in back of a shed and shoot it with a double-barrel shotgun" (or something of that sort), but that's like shooting Morrowind infant son as well.
