Cy (Shuck)

Cy is a shuck that speaks telepathically
We met Cy and Laura fishing at a lake. Cy gave the Apple Squadeth a ride saving them a bunch of travelling time. 
We meet Cy again at the killing ground where he has been captured and forced to fight to save Laura, who they have convinced him that they have trapped and will torture. 
Banffor convinces him in return to fight the monster with him and then transport them to the opposite shore.
