The Erabenimsun Tribe is one of the four Ashlander tribes of Morrowind. The Erabenimsun are primarily warriors who esteem strength. They have little time for Imperials, prophecies, or indeed anything other than themselves. Under their current leadership, they are little more than brutes: of their nobles, only one is capable of seeing beyond "survival of the strongest", and he is the weakest of the leaders - although he has the support of the wise-woman, he cannot become the tribe's ruler and deal more wisely with the outside world, without outside help.
There is a chance that some members of the tribe will simply attack you for asking questions. In fact, so great is their xenophobia that when you hear the story of Imperials stealing their herds for hides, one is tempted not to sympathise with them, even though they are for once in the right.
