Feel free to make your own story up if you like to.
Look at the above map, where and how do you think you will begin? Given the tradition that we start in prisons or something similar and that we probably won't begin at a major town. Where and how?
I think we'll begin at Lakvan's Stronghold, a key character will enter the room to break you free from prison since there's a monster/bandit raid and he uncuffs/unties you. Tutorials will initiate from here on until you exit the building, some important event will happen causing this character to break loose from you and he tells you to grab the nearest weapon and meet at X location (still in the building). After fighting some monster/bandits and re-joining with the key character, you both exit the building. Here, you see a dragon come flying down and he begins to fight it (AI vs AI) in a brief cutscene. He dies/flees/gets severely injured and you are forced to fight the dragon, where you realise help arrives in a few minutes. When they do, they hold off the dragon and you are brought to Snowline town where you're free to do as you wish.
These people reveal themselves to be The Blades and also reveal their hidden location to you. They say the dragon can return anytime soon so be prepared, you then fight and kill the dragon, making your first dragon "capture".
After this, the game's yours!
