The war formation had been finalized. A joint discussion was held after Shan and Peter had come up with their ideas, then Leon took it all in and created a new, more detailed formation from both of them as well as from himself. Gretta agreed to that.
Now there was one more thing they had to determine. Who would move first? Rhys or Mat? That estimate was very important and would definitely affect them. The battle array prepared was obviously different to deal with the two people.
From Leon himself, the prediction that would advance first was Rhys. This was not without reason, the first consideration was the fact that Rhys no longer had a beneficial relationship with Mat. He had been hunting Mat because of the existence of Amethyst in Mat's hands, but not anymore.
The second consideration, Mat did have a strong relationship with Leon and also Gretta, but his own troops had a bad bond with Rhys. Which means, he will move after his troops move forward first.
