A conversation with Abzrolg will uncover that he has been researching Orsimer clans for the past three years. This has made him realize how little he actually knows about his own people.
"The guild asked me to research Orc clans. I thought the assignment would take me a week. That was three years ago."
Have you learned anything interesting?"Only how little I know about my own people! Clans appear and disappear as time passes, yet each contributes in some significant way to our culture. For example, take Morkul clan."
What about them?"Morkul clan can be traced back to Old Orsinium—beyond that, actually. They disappeared for centuries after the fall of Old Orsinium, then once more revealed themselves to Tamriel. I have asked where they went, but it is apparently a clan secret!"
