I will be a nice guy, to begin with, then while the wool is firmly upon their eyes i will swoop in and rule Albion with a muffin flavored fist. All I ever wanted was to be a good guy...then beat out the blood of those who accepted me(but were ultimately NPCs to begin with and to the end).
Of course I will just hide my dastardly deeds and blame it upon a jester who had a little to much dragon tears one night. Then systematically all the important people will be out of the way with only me, Mr. McNice-person to lead them...into a lake of fire and pointed sticks.
