Is the leader of the Fighters Guild in Cyrodill just over Cyrodill or is he/she THE Grandmaster of ALL Fighters Guilds world wide? (This also applies to any and all joinable factions, including the Dark Brotherhood and Thieves Guild, which are less...legal and public but no less organized.)
One reason I ask is that in Morrowind it seems to be implied that the then Cyrodill Archmage, Ocato of Firsthold, had some authority at asking Trebonius to step down. Of course he was also the Imperial Battlemage at the time and it might be his authority at that station he was speaking from, not his position as Archmage. I'm wondering if each province's Guild has its own head honcho who answers to nobody or if Gentleman Jim Stacey, for instance, has any connection to or obeys orders from the Gray Fox, or perhaps more officially, assuming the Nerevarine left the Fighters Guild in the able hands of Percius Mercius in Ald-Ruhn, does Mercius answer to the Champion of Cyrodill? (or Modryn Oreyn after the CoC inevitably disappears to Akavir or some Outer Realm never to be seen again)
Or perhaps are the Guilds autonomous, following some guidelines but with no central leadership? I noticed a lack of contracts or orders all the way from Cyrodill when playing Morrowind. When you were promoted to head of a guild there, it was pretty much at the discretion of the acting leader or in the likely case of his demise, the second in command to name you leader. No waiting three months for a letter from the Cyrodill Guildmaster. It was just right then and there, you're Grandmaster. This leads me to believe that the Provincial Guilds are by some degree autonomous and don't answer to their Cyrodill counterparts to any great degree.
And of course in the case of the Dark Brotherhood, Vvardenfell had its own http://www.uesp.net/wiki/Morrowind:Severa_Magia, and Mournhold also had a http://www.uesp.net/wiki/Tribunal%3a%44andras_Vules. (In the case of the Night Mother, she may have been some kind of Avatar or mortal shell for the actual Night Mother. Or maybe it's a coincidence she's an Imperial Female and everything - I doubt there are any true coincidences.)
