So this brings me to my topic. If Bethesda ever release an ES game in the future that has a GIGANTIC map and explores all of Tamriel, then what story or piece of lore would best be used to take advantage of such a setting?
My choice would have to go for Barenziah and searching for the eight pieces of the Staff of Chaos to defeat Jagar Tharn. A return to Arena although modern and updated.
The game would begin with a cinematic opening explaining the life of Barenziah, running away with Straw to Riften, her becoming Queen of Mournhold at 18 etc, right up to her discovering Uriel Septim VII is actually Jagar Tharn. The game then begins with you in the Imperial Dungeon. I want to give the prisoner, this 'Champion', a name. It will be 'Colin', he will be a Breton, and he will be a Master of Magicka!
From 'Biography of Barenziah, v3', "As all now know the courageous, indefatigable, and forever nameless Championwas successful in reuniting the eight sundered pieces of the Staff of Chaoas"
So the main advantage of using this story is that you have a reason for exploring all of Tamriel. And there is the possibility of a good ending which is satisfying in the form of a 'grand state memorial service' which is held for Symmachus.
So if you had a future ES game which used the whole of Tamriel, why piece of Lore/storyline would you like to explore and why?
