Imca: You have the Winterhold College correct? And you have bloody powerful magic dragons, can mages here combine their power? If so, gather all the mages you can, put all the power into one large spell... and just wipe this continent here.
(Imca points to the one with the knife in it.)
Imca: Off the map. Show people what happens when any one entity tries to control the world like the Thalmor are trying...
Aurora: ...well... that would probably end the war, but...
Aurora: ...but would that really be worth it? Eradicating an entire Island full of not only Thalmor, but also civilians, just to prove a point?
Imca: There are two things about this: you first deliver an ultimatum, and start somewhere a bit smaller to show them that you can, if they still don't back out you work up.
Imca: Committing such an action, will change the progression of history, as all other nations will come up with their own variations of this, while in the short term it is a horrible thing to do, in the long run it renders large scale war a thing of the past as no nation is willing to push the button, so to speak.
