While Commander Isaac was chasing Bushwick, the nobles were fighting a war with the Church of Justice and were winning. This came as a surprise to everyone who heard about this, including the nobles.
The nobles couldn't believe that they were beating the church of justice in every battle because they didn't think they had such power.
Any noble with some knowledge about history would say that the power of nobles has fallen to a very low state. Even nobles who are ignorant of history and only know current affairs will remember that it was just recently that their king was taken from the palace and killed by a lamp bearer.
The disrespectful abduction of the king and the subsequent beheading of the king were almost 100 years ago. This might be a long time to mortals, but to godclads, it is just half of the lifespan of an epic godclad and one-fifth the lifespan of a legend.
