Imagine the scene: on a headland not far from Dublin, a mother and her young son look out to sea. On the horizon, they can make out a range of mountains. Gwynedd, she tells her son. There is your father's kingdom – teyrnas Cynan. He had to flee, leaving his kingdom – but one day you will return. You will become King of Gwynedd! A Welsh adaptation of Gwres o'r Gorllewin.

Dychmygwch yr olygfa: ar benrhyn nepell o Ddulyn, saif mam a'i mab yn edrych allan ar y môr. Ar y gorwel, gwelant res o fynyddoedd. Gwynedd, dywed y fam wrth ei mab. Dyna deyrnas dy dad - teyrnas Cynan. Bu'n rhaid iddo ffoi, gan adael ei deyrnas - ond byddi di'n dychwelyd yno ryw ddydd. Byddi di'n Frenin Gwynedd! Addasiad Saesneg o Gwres o'r Gorllewin.
