Although they no longer had Ray's system to communicate between each of the members, there was something else they could use and it was one of the reasons why Lenny had been brought along.
It would take some time, but before leaving, a communication magic circle had been set up at Avrion. Now Lenny could draw a magic circle at their current location and could use it to communicate with Bliss.
In the time while they waited for Lenny to draw the circle, Monk and the Dark Guild members had already left. He promised that they wouldn't disturb the Redwings, he could do that much. However, whether he could convince a long time old foe of Avrion to fight alongside them was a different matter altogether.
