Just couple ideas for DLC Bethesda could do...

I personly dont want to see a new elder scrolls...main reason way is im tired of starting over and its always the same your a prisoner =P
Skyrims alot of fun and i would like to see the story and adventure keep going.

1st Idea for a DLC/Expansion:
Saving Talos, Players would be summoned by Talos to His releam to aid him.
You would find out maybe the Aldmeri Dominion, created a curse that binded Talos to his Spirit releam and block him from content to the real releam and to his followers.

After helping Talos you would find out you are the Daughter/Son of Talos and be given powers to let u Telaport to his releam and gifted with Armor named after you and a Title Demi Goddess or God of Talos.
Maybe even a story where u help restore the 8 diven back to being the 9 diven and now u are the 10th divin Daughter of Talo or Son of Talos.

2nd Idea of DLC/Expanion:
Rise of the Nords,
You would help the Nords/Skyrim Fight the Aldmeri Dominion By trying to get the Support of High Rock where the Aldmeri Dominion is trying to take controll over.
You will then get the support of the Bretons and Also earn many of the Thanes of Skyrims support leading you to have to fight
Ulfric Stormcloak or fight General Tullius and get him to support you.
You will then be High Queen or King of Skyrim.

3rd idea DLC/Expanion:

Hammerfell's Liberty,
You would help Liberate them from the Aldmeri Dominion you will find that the Aldmeri Dominion has already taken over Hammerfell and made it a strong point of a forward base Many of the Aldmeri Dominions armys would be here so you will have to seige and invade with high rocks bretons and the Nords to libertrate the Redgurads where u Save there King from being captured and in slaved by a mind spell that controlls him.

4th idea DLC/expanion:

The Rise of the New Empire:
You will get a quest from a emissary sent by a high chancellor proclaiming you a traitor to the Empire.
you will then seak the redguard king and leader of high rock aiding you agest Cyrodiil.
You will fight and try and get the support of the citys and there leaders.
After you seige and capture citys you wil then try and get them to support you once you earned all the citys supports you will then have a final siege for the Gold tower.
After wards you will be proclaimed the New Empress or Emperor of Tamriel.
They will call you Empress Dovahkiin or Emperor Dovahkiin.

After you will then get to chose out of a few companions u got to support u to be your High Chancellor each would have a diffrent personalty that would effect how they run the empire when u are gone and exploring also each offer diffrent ideas to Govern the new founded Empire and offer you with a option to repopulate a city and rebuild it for septims.


5th idea DLC/Expanion:

The fall of the Aldmeri Dominion,

This would be where you now find out you cant sail to Summerset Isles with a fleet or a army cuz the Aldmeri Dominions mages would sink any ship before it ever saw there home land.

So you Deside to ride on a Dragon to there home land from above where they are not prepaired for. from the gold tower.

You alone will find out there is a coral betwin Familys of the Aldmeri Dominion for controll and you will chose what house to support and help them in return for there support for you.
You will then prove your self to that house/Family and after you have proven your self you will help them be the new Leading House of the Aldmeri Dominion where they trick you and capture you and place u in there prison to wait excution.
You will have to escape there prison and make your way out where you find others Nords and allies from the battle in Hammerfell that you have to Rescue.
Once you make it out of the prison you deside to get revenge and you call for help where 5 dragons come to aid you and your allies all 5 of you will ride on the backs of the dragons and fight the Aldmeri Dominions Main city and keep where the houses/familys surrounder to you and fear the Dovahkiin Daughter/Son of Talos.

6th DLC/Expanion:

Im out of ideas thats all i came up with for now =P

Hope you like the ideas this is a few ideas i feel Bethesda should try and do or make simler ideas to add for skyrim.
I mean your a Vampire lord you Can beat the first Dragonborn you can have dragons come to your aid and ride Dragons.

I mean if bethesda deside to create a new elder scrolls i would be pissed with skyrim can be so much and offer so much content that a new elder scrolls could never top wth where skyrims story can keep being or lead to.
I really really hope Bethesda creates content like these for Skyrim or simlier if not ill hirer a Game team and make free expanions for it =)
