The Silurian, Book Three, Longhand, White-tooth, and the Fox:

A GREAT PRINCE ARISES

The Fox is taken prisoner by the Dynasty of Cadwallon Llawhir, the Longhand, and his cruel and ambitious brother, Owen White-tooth, both of the powerful clan of the Gwynedd Gododdin, who seek to keep Arthur from rising to take absolute rule of Britain as Imperator, and they do this by seizing Prince Bedwyr for themselves. Taken from the Clan Bear, the Fox is forced into the army of Cadwallon Llawhir to fight for the Men of Gwynedd, and used in the hope of thwarting any further rise of Arthur’s power, for only Bedwyr knows how Arthur fights and wins, only Bedwyr knows the Silurian’s heart and way, and for it, Longhand imprisons the Fox in his stronghold of Rhos: here Bedwyr is forced to marry into the Dynasty of Longhand and White-tooth, here he is abused and beaten, yet he rises above the savage manipulations of his own kinsmen to survive long enough to join with Arthur again. Now called the Red Ravager, Arthur, the young warrior who hammers the great Angle Atheling Colgrin, in battle after battle, causes Owen White-tooth to leave Gwynedd and challenge Arthur on his own home soil. 
 

Away from Arthur's battles, the Fox’s journey is no less painful, and his wait is arduous. And it is here, separated from his beloved foster-brother that Bedwyr becomes a powerful prince and warrior in his own right: a man that other warlords fight over to gain for themselves the power of the Fox’s sword-arm. But Bedwyr is sworn only to Arthur, and he waits for the inevitable day when Arthur invades Gwynedd with his army to claim back his lost brother…
