Will we get to see the Trinity Raven again? it's been so long after the Tower of Heaven incident. They were mentioned to have wiped out every single officer of the Western Army in the Cabria War.

I think the Western Army is the Albareth Empire's since Alakitasia is in the west and the Cabria War might be the invasion from the Western Continent. I also believe that the trio of elite Mage assassins were hired to kill the top officers with efficiency by Magic Council (if they're willing to use Dark Guilds in defense of Isghar) or by one of Isghar's country's army.
