Secondly, I will use "Resdayn" in place of "Morrowind", and "Argonia" in place of "Black Marsh". Both provinces were renamed following the invasion of Tiber Septim, which is centuries after this game takes place.
Finally, I'll include a bullet note summary at the end.
Now I read the lore article on the game's Facebook page, and I saw this:
[Skyrim, Resdayn and Argonia] allied to form a new power, ruled over by the Great Moot, a council of equals from all three races.
When I read this, I felt disappointed. It makes far more sense for the Grand Council to rule the Ebonheart Pact, rather than the "Great" Moot. The Grand Council has more is more ancient and proven body of government.
I would like to draw your attention to this "Great Moot." First off, the Moot in Skyrim is not a legislative body, rather a temporary body that only meets and has any degree of power when Skyrim lacks a high king, and even in that case the Moot's only power is to name the new high king. I suppose Great Moot would imply unprecedented legislative and executive power, so I figure that's a mute point (ba-da-bum-tiss).
My greater issue with this piece of information is the apparent discrimination against the multiracial legislative body seated in Ebonheart, the one known as the Grand Council. The Grand Council was created as an interracial governing body to bridge the gap between the Dwemer and Chimer. Facing an outside threat, the Chimer and Dwemer put aside their differences to form the Grand Council and the mixed-race nation of Resdayn. The Ebonheart Pact is built on the same principle. Even after the Dwemer went extinct, the Grand Council continued it's spirit of unity. The occasional scuffles between the Houses were minimized, and House Hlaalu is know to elect "outlanders" to the Grand Council.
Now that I've been over some of the merits of the Grand Council, it is more than important to cover why the Grand Council should take priority. Firstly, Resdayn is the geographic center of the alliance, which is why it's called the Ebonheart Pact. The Grand Council is seated in Ebonheart, so it doesn't take much imagination to assign leadership to the Grand Council. Secondly, the power of the Great Houses (currently numbering 5, plus 2 "dead" ones) is self-reinforcing, politcal power would be centered on the Houses. The Houses make up the Grand Council. Thirdly and Finally, the Earthly-bodied Gods of the Tribunal live in Resdayn and have invested their power in the Grand Council. While each member nation of the Pact has it's own King and/or Queen, Gods typically take precedence over royalty.
[Edit:] The Grand Council would be made up of equal parts Dunmer, Nords and Argonians.
To Summarize:
- The Moot, Great or normal, has no legislative or executive power.
- The Grand Council historically maintained power in Resdayn.
- The Grand Council was made to keep peace between bitter enemies.
- Resdayn, and furthermore Ebonheart, is the center of the Pact, and it's only sensible to grant administrative authority to the Grand Council.
