Ever wonder why there was no real hierarchy to the Great Houses? Why there was the Grandmaster, then the Councillors, and then a strange hazy sort of blur of lower rankings? Is that any way for a political entity to function? Nope, I didn't think so either.
Now there is a proper structure to House Hlaalu, with actual governers for Suran and Gnaar Mok, not just Caldera. The Treasury actually has a master now, and the Hlaalu quest givers have an official title.
Rankings were adjusted to make more sense and now the player can actually become a Councillor - something that was impossible in the original game for some unknown reason.
You can even talk to your subjects about local concerns when you reach the appropriate rank. Features a new "Yellow Register of Hlaalu" which lists all senior members from the rank of Kinsman upwards, including the player, which is updated as you gain standing in the House. Just see the Grand Hlaalu Scribe in Hlaalu Records, Vivec.
