'The Romans have magnificent weapons – but we the Britons have enough fire in our hearts to melt metal!' These were the words of Caradog, the bravest of kings. He is hero-worshipped by Morcant, the young Silurian, whose dream is to follow his hero to free his country from the Romans.

'Mae gan y Rhufeiniaid arfau gwych – ond mae gyda ni'r Brythoniaid dân yn ein calonnau all doddi metel!' Dyna eiriau Caradog, y dewraf o frenhinoedd. Caradog yw arwr Morcant, y Silwriad bach. Breuddwyd Morcant yw dilyn ei arwr a brwydro i yrru'r Rhufeiniaid o'i wlad.
