I've heard somewhere that some stuff were inside the game but later then got cut off, for example:

1) Releasing Thorald from the Thalmor if you joined the Legion.

2) Having Balgruff killed and have his brother take on the Jarl's throne

3) Getting rid of Elisif

Again, I only heard this from various places, but I'm not sure if they are true or not.

If they are indeed true, is it possible to restore them or they are gone forever?
