Then William checked over the formation of the two teams.
Each leader spread the word, and lots of masters wanted to join the fray. Yet they waited for William to get the last word from him about this.
"Having too many is going to be bad, let's stick with one hundred masters per leader," unlike what they expected, William refused raising such a number.
The latter didn't limit the number thanks to his worry over the masters' rejection or something. William knew how masters were courageous and loved to defy any odds. And that wasn't why he set the number to one hundred per leader.
He did so as there was something that he didn't find a trace of yet, a nasty formation that could divide an army into groups of a hundred or so. If there was a single master in the group who didn't have any loyalty with the group, then things would grow bad for everyone.
