"So, what did you want to discuss with me, Mr. Cerni?" Rui asked tentatively.
"I wish to discuss the modus operandi that I hope you will be engaging in when completing the mission," Feruir Cerni replied. "I wish for you to spare the lives of the crew of the convoy while wearing a particular Martial garb of another nation. I require you to kill the Martial Squire, followed by handicapping and incapacitating the convoy."
Rui immediately understood the motive of the mission.
('He wants to compromise the supply line of the Commonwealth Duchy of Vinfrana coming from the Kingdom of Violis and frame it on another nation or group.') Rui realized.
There was no other reason to have Rui wear a separate Martial garb and spare the crew of the supply shipment convoy.
