You're all thinking FAR too small. First, Thedas, and then the world!
Once the world has been brought to heel, the next target is the Fade itself and a Quest for immortality. Once that is done, I shall start MY people, Human, Elf, Qunari, and Dwarf upon a grand quest. We WILL advance our technology until we acquire Space travel. With the stability provided by MY Immortal reign we shall expand out into our solar system and then onto the Galaxy.
My people will become the new ruling class in a Star Spanning EMPIRE and I shall be their beloved, Immortal, God-Emperor!
and then...only then....will peace and order flourish across the galaxy.
...until it's time to conquer the next dimension.
because when I say I am going to 'rule it all' I mean it!
