Damien along with his undead slave, Tristen walked towards the barrier which was opaque white, making it unable to see what was inside when usually ethereal barriers are transparent.
With this, he realized that someone who was a master in formations had created this barrier.
Since he had no idea how to exactly 'knock' on this barrier, he made Tristen say aloud, "Your Majesty, King of Shizar, I am Prince Tristen of the imperial family, here to offer a diplomatic solution to all of our problems. All I request is an audience with you for a few minutes to talk. I hope you would agree to this so that we can do without any needless bloodshed."
Damien knew officially it was still the ten-year-old boy who was the king of Shizar in name, and thus it was only right to address him instead of the Forsaken, especially since the Forsaken weren't the rulers officially.
