If it was not because of one of the letters Chester Silas had given me, I would never know about Azrael as being a Directive Special Knight.
'... He might have to die by burning for that reason too.'
According to his letters, alongside asking me to meet him, he also warns me about Azrael.
He was warning me about Azrael as being a part of the Special Directive Knights.
Azrael de Revanche Second Order.
Azrael, as a Directive Special Knight, never stepped foot outside his manor and would never patrol around the kingdom.
With an exception of accepting a mission from Edward Agersia First Order himself.
Chester asked me to take that advantage and use Azrael to escape Lucretia because Chester found something and a way to step outside Lucretia to see the outside world.
'... But, there was a slight problem here.'
At the end of the letter, Chester has also mentioned the chances that Azrael will cooperate with me is very low.
It was estimated to be only 5%.
