Caradog is the grandson of the sea god Llŷr, the nephew of Manawydan, Branwen, Efnisien and Nisien.
Matholwch is deeply offended until Bran offers him compensation in the form of a magic cauldron that can restore the dead to life.
She tames a starling and sends it across the Irish Sea with a message to her brother Bendigeidfran, who raises a huge host in preparation for invasion.
A council is held among the British and it is decided that seven men should stay behind to defend Britain; Bran's son Caradog is given seniority over the chieftains, namely Hefeydd the Tall, Unig Strong Shoulder, Iddig ab Anarawd, Ffodor ab Erfyll, Wlch Bone Lip, Llassar fab Llasar Llaes Gyngwyd and Pendaran Dyfed.
Caradog's paternal uncle Manawydan learns of his nephew's death upon his return from Ireland and submits to the usurper.
