Doman Timeline

[treuhavik]

Given that Karasu was a Doman shinobi, I'm inclined to believe that this revolt went on for a while, maybe a few earth months. Thinking this way allows the Empire the time needed to assess the situation and set in motion their plan; Flip a high-ranking shinobi and have him end the resistance from the inside. Ultimately, the rebellion failed and I'm sure it was due to Karasu's betrayal, massacring the only force the Domans had against the empire.

So, the betrayal? Definitely at the end, or at least latter half.

Didn't the betrayal was for conquering Doma and not his destruction ?
Spoiler Ninja storyline :

Because the ninja master comes to track him down without saying anything about destructing, Doma, he only speaks of heavy represions after the end of the war, which are obvious considering how the empire handle his conquests. It seems that he comes to track the traitor before 2.2, if not it might have been weird to send Ninjas track a traitor while they are trying to escape from the empire killing every domian around, moreover the traitor had enough time to greatly train a lot of ninjas for the empire and it must have taken a while between the betrayal and the NIN storyline.

But these ninjas don't come from Doma directly ( they aren't the same as Yugiri's ) but come from a secret village close to Doma so maybe the master doesn't know what happened very clearly.
