What if the Order had murdered the Linear Guild

It might also be that Odin, not being omniscient, gets like flashes or insights into the future, so he knows he wants Durkon exiled but he can't really foresee the exact developments that will cause him to help Odin's cause/go back to Dwarven lands bringing death and destruction. In mythologies, Fate is typically a wholly independent force of which the gods get very imperfect glimpses. Prophecy is totally up Odin's alley, so he would get more exact glimpses than most deities, but there's no reason to assume he's remotely close to omniscient.
