At the minute the roleplay is fairly linear, the major side quest lines only being touched upon, however after te first half of the rp it'll become a great deal more sandbox freedom being completely unrestricted.

And single handily killing dragons were achieved by the heroes of old, yes. But at the minute we are novices in the dragon killing game, they were experts, so it may be possible late in the roleplay, but at the minute? No.

Strictly speaking we are sticking to the lore, however you are free to change it, so long as it is cleared by me and the other gms and it isn't anything massive, like killing Martin before he turned into Akatosh, etc.

And finally you're free to make anything you wish in terms of armour, weapons and spells, within reason.

Hope I answred everything.
