Does anybody know the Great Houses of Hammerfell? one of them was mentioned in the "In My Time of Need" Quest in skyrim, but I don't remember what it was called. Is this the only known house or are there others?

I think thats the only one we know of. Most of the happenings (political and cultural) arent all that well known in Hammerfell (and most of the other countries

Yeah, but you know what it's called? the name is mentioned but it's not written on any of the wiki's for some reason.

I think it was Suda or something along those lines

Yeah, that sounds familiar...
