As a thread starter, I’ll copy over the conversation from the PT thread from a while ago.

The Redoran questline (still in discussion) is thought to start as a minor conflict with House Hlaalu, but will eventually evolve into an effort to keep the native Nords, the Nail-Knock Reavers, pacified.
A big part in this will be where the Reavers got the money and arms to stage their uprising from.

The obvious culprit is the Thian's kingdom, Haafinheim (Solitude).

To recap, in TES canon the Kingdom of Solitude:

• As of The Pocket Guide to the Empire, 3rd Edition, have occupied Roscrea
• As of The Pocket Guide to the Empire, 3rd Edition, are going after all Imperial Territory they can
• As of Oblivion in-game dialogue, are in the process of occupying Solstheim and beating the Redoran black and blue
• As of Skyrim dialogue and books, gave Solstheim to the Dunmer as a show of support, which implies that they owned it as thoroughly as they could prior to the 4th era

I feel it would be helpful to coordinate how Haafinheim develops during Shotn's questline and how it would fit into the timeframe of TR's Redoran questline. As Oblivion (its fractal terribleness aside) is still the best view into Tamriel's future, I think Haafinheim's slow digestion of Roscrea and slow grasping towards Redoran territory (and Solstheim) is something that we could bounce off each other.

First and foremostly, we need to settle on a final name for the hold. If TR want to reference Solitudes expansionism, they will probably refer to it either as Solitude or Haafingar. Not sure if it would make sense to establish the non-canon name Haafinheim, as it might be offputting to outside people.

Also, I've recently written up some keywords on how Haafingar has been planned on our part so far, if that helps anything:

There has also been discussion on a possible secret police in the service of King Thian. Ruthless elite warriors, led by a core of vampire generals that survived the defeat of Queen Potema. We wanted to name this subfaction "Oprichniki" (Oprichnek), but that name has been critizied, as it's basically the name of a group of a russian warrior caste of real world history. The idea for the name came up in the early days of SHOTN and can be changed at need.

Thian being the culprit here would surely make sense. He has probably sent a vassal, an agent of the elite group worsas mentions, to carry out this covert operation.

That name is at least two forum transitions old. We will find a new name.

How about the Vorgas Guard?
