Each one of them felt mixed emotions after hearing Kyran's plan.
They were not afraid, nor were they against it. Instead, they felt Kyran's plan was too ambitious. Knowing that he wanted to start the first part of his plan in a month's time was already challenging.
The roles Nolan mentioned each of them would do, were not hard to fulfill.
At first, Silas and Gage were nervous to hear what they had to do. They felt they lacked the means to complete whatever was required of them. After hearing what it was, they were relieved.
Most of what they had to do was manpower gathering and acting as the point of contact, which they both experienced as mercenaries.
Kyran emphasized that they must keep anything they do a secret from the Conclave.
Although his clan had ties with the Conclave, he did not want to get them involved in his matters. Besides, what the Conclave knew about the situation was still superficial compared to Gage and Silas's.
I did not go through all the details of their talk because I am afraid it would take a lot of chapters. Instead, I planned to slowly reveal it in future chaps :)
