I would love to see the fighters guild return as well as the disbanded mages guild.

I'd like to see Beth do a setup like Morrowind, with a local province faction and matching Imperial faction for each character archetype.

So just to speculate:

Imperial Guilds:
Fighters' Guild
Synod
College of Whispers
Thieves Guild
Dark Brotherhood
Imperial Cult
Imperial Legion
Cult of Talos?
Pentius Oculatus?

And like I already said, I'd like an equivalent group local to the province for TES VI for each group.

The only question? Where is TES VI gonna take place? Elsweyr? Alinor? Black Marsh? I'm guessing Alinor, it seems only likely.

Alinor is not a real province, it is just the name aplied by the thalmor to the "occupied" provinces of Valenwood, Summerset Isles, Etc.

They renamed the Summerset Isles to Alinor before the annex (I guess you'd say) of Valenwood and Elsweyr. I suppose I was implying Summerset Isles. Oh well.

If they set TES VI in Alinor, I'd like to see some Thras and [MAORMERCONTINENTTHATISHARDTOSPELL] mixed in there too.

Of course, Summerset was supposed to be the setting of TES III when TES II was supposed to be Morrowind, before the Daggerfalled everything to High Hrothgar.

I'd like to see what they have in store for us!
