The Avatii are a secretive sect of warriors. They are feared across the land, they are easily identified by the masks that they always wear. It is considered shameful for an Avatti to speak to someone who is not of the Avatii and as such it is a task delegated to the lowest ranking member present. Holding a weapon and looking at an Avatii is considered a challenge and in most cases results in swift death. Someone who slays an Avatti takes their standing and may be spoken to by the other Avatii. The masks are the symbols of rank, the more ornate the mask the lower the rank. There only 100 Avatii at any time. No one knows what guides the Avatii but those who know them or have met one know to step aside and concede their cooperation and support. Many consider them to be legends as they have never seen one in person.
The Avatii were formed as a personal bodyguard of the founding Emperor of the Assail, Hedge Dev. After his death they broke from the empire and became a reclusive sect of the God of High House War. During a rare time of unity for the Silchas the Assail, Masten, and Tiiren sent armies to combat the Silchas forces and disperse them, the Avatii sent a punitive army down consisting of three swordsmen and cut through the Silchas forces with no losses, killing as many as any of the other three armies. Reports from the Assail forces say that among the Silchas on the Avatii front there were no wounded, only dead, yet, after the battle they just walked away.
